Subject: [PATCH] drm/vc4: hdmi: Make sure the device is powered with
CEC
Similarly to what we encountered with the detect hook with DRM, nothing
actually prevents any of the CEC callback from being run while the HDMI
output is disabled.
However, this is an issue since any register access to the controller
when it's powered down will result in a silent hang.
Let's make sure we run the runtime_pm hooks when the CEC adapter is
opened and closed by the userspace to avoid that issue.
Fixes: 15b4511a4af6 ("drm/vc4: add HDMI CEC support")

Subject: [PATCH] drm/vc4: hdmi: Warn if we access the controller while
disabled
We've had many silent hangs where the kernel would look like it just
stalled due to the access to one of the HDMI registers while the
controller was disabled.
Add a warning if we're about to do that so that it's at least not silent
anymore.

Subject: [PATCH] drm/vc4: hdmi: Remove the DDC probing for status
detection
Commit 9d44abbbb8d5 ("drm/vc4: Fall back to using an EDID probe in the
absence of a GPIO.") added some code to read the EDID through DDC in the
HDMI driver detect hook since the Pi3 had no HPD GPIO back then.
However, commit b1b8f45b3130 ("ARM: dts: bcm2837: Add missing GPIOs of
Expander") changed that a couple of years later.
This causes an issue though since some TV (like the LG 55C8) when it
comes out of standy will deassert the HPD line, but the EDID will
remain readable.
It causes an issues nn platforms without an HPD GPIO, like the Pi4,
where the DDC probing will be our primary mean to detect a display, and
thus we will never detect the HPD pulse. This was fine before since the
pulse was small enough that we would never detect it, and we also didn't
have anything (like the scrambler) that needed to be set up in the
display.
However, now that we have both, the display during the HPD pulse will
clear its scrambler status, and since we won't detect the
disconnect/reconnect cycle we will never enable the scrambler back.
As our main reason for that DDC probing is gone, let's just remove it.

Subject: [PATCH] drm/vc4: hdmi: Raise the maximum clock rate
Now that we have the infrastructure in place, we can raise the maximum
pixel rate we can reach for HDMI0 on the BCM2711.
HDMI1 is left untouched since its pixelvalve has a smaller FIFO and
would need a clock faster than what we can provide to support the same
modes.

Subject: [PATCH] drm/vc4: hdmi: Add a spinlock to protect register
access
The vc4 HDMI driver has multiple path shared between the CEC, ALSA and
KMS frameworks, plus two interrupt handlers (CEC and hotplug) that will
read and modify a number of registers.
Even though not bug has been reported so far, it's definitely unsafe, so
let's just add a spinlock to protect the register access of the HDMI
controller.

Subject: [PATCH] drm/vc4: hdmi: Use a mutex to prevent concurrent
framework access
The vc4 HDMI controller registers into the KMS, CEC and ALSA
frameworks.
However, no particular care is done to prevent the concurrent execution
of different framework hooks from happening at the same time.
In order to protect against that scenario, let's introduce a mutex that
relevant ALSA and KMS hooks will need to take to prevent concurrent
execution.
CEC is left out at the moment though, since the .get_modes and .detect
KMS hooks, when running cec_s_phys_addr_from_edid, can end up calling
CEC's .adap_enable hook. This introduces some reentrancy that isn't easy
to deal with properly.
The CEC hooks also don't share much state with the rest of the driver:
the registers are entirely separate, we don't share any variable, the
only thing that can conflict is the CEC clock divider setup that can be
affected by a mode set.
However, after discussing it, it looks like CEC should be able to
recover from this if it was to happen.

Subject: [PATCH] drm/vc4: hdmi: Prevent access to crtc->state outside
of KMS
Accessing the crtc->state pointer from outside the modesetting context
is not allowed. We thus need to copy whatever we need from the KMS state
to our structure in order to access it.
However, in the vc4 HDMI driver we do use that pointer in the ALSA code
path, and potentially in the hotplug interrupt handler path.
These paths both need access to the CRTC adjusted mode in order for the
proper dividers to be set for ALSA, and the scrambler state to be
reinstated properly for hotplug.
Let's copy this mode into our private encoder structure and reference it
from there when needed. Since that part is shared between KMS and other
paths, we need to protect it using our mutex.

Subject: [PATCH] drm/vc4: hdmi: Check the device state in prepare()
Even though we already check that the encoder->crtc pointer is there
during in startup(), which is part of the open() path in ASoC, nothing
guarantees that our encoder state won't change between the time when we
open the device and the time we prepare it.
Move the sanity checks we do in startup() to a helper and call it from
prepare().

Subject: [PATCH] drm/vc4: hdmi: Introduce an output_enabled flag
We currently poke at encoder->crtc in the ALSA code path to determine
whether the HDMI output is enabled or not, and thus whether we should
allow the audio output.
However, that pointer is deprecated and shouldn't really be used by
atomic drivers anymore. Since we have the infrastructure in place now,
let's just create a flag that we toggle to report whether the controller
is currently enabled and use that instead of encoder->crtc in ALSA.

Subject: [PATCH] drm/vc4: hdmi: Introduce a scdc_enabled flag
We currently rely on two functions, vc4_hdmi_supports_scrambling() and
vc4_hdmi_mode_needs_scrambling() to determine if we should enable and
disable the scrambler for any given mode.
Since we might need to disable the controller at boot, we also always
run vc4_hdmi_disable_scrambling() and thus call those functions without
a mode yet, which in turns need to make some special casing in order for
it to work.
Instead of duplicating the check for whether or not we need to take care
of the scrambler in both vc4_hdmi_enable_scrambling() and
vc4_hdmi_disable_scrambling(), we can do that check only when we enable
it and store whether or not it's been enabled in our private structure.
We also need to initialize that flag at true to make sure we disable the
scrambler at boot since we can't really know its state yet.
This allows to simplify a bit that part of the driver, and removes one
user of our copy of the CRTC adjusted mode outside of KMS (since
vc4_hdmi_disable_scrambling() might be called from the hotplug interrupt
handler).
It also removes our last user of the legacy encoder->crtc pointer.

Subject: [PATCH] drm/vc4: crtc: Rework the encoder retrieval code
(again)
It turns out the encoder retrieval code, in addition to being
unnecessarily complicated, has a bug when only the planes and crtcs are
affected by a given atomic commit.
Indeed, in such a case, either drm_atomic_get_old_connector_state or
drm_atomic_get_new_connector_state will return NULL and thus our encoder
retrieval code will not match on anything.
We can however simplify the code by using drm_for_each_encoder_mask, the
drm_crtc_state storing the encoders a given CRTC is connected to
directly and without relying on any other state.

Subject: [PATCH] drm/vc4: Leverage the load tracker on the BCM2711
The load tracker was initially designed to report and warn about a load
too high for the HVS. To do so, it computes for each plane the impact
it's going to have on the HVS, and will warn (if it's enabled) if we go
over what the hardware can process.
While the limits being used are a bit irrelevant to the BCM2711, the
algorithm to compute the HVS load will be one component used in order to
compute the core clock rate on the BCM2711.
Let's remove the hooks to prevent the load tracker to do its
computation, but since we don't have the same limits, don't check them
against them, and prevent the debugfs file to enable it from being
created.

Subject: [PATCH] drm/vc4: Increase the core clock based on HVS load
Depending on a given HVS output (HVS to PixelValves) and input (planes
attached to a channel) load, the HVS needs for the core clock to be
raised above its boot time default.
Failing to do so will result in a vblank timeout and a stalled display
pipeline.

Subject: [PATCH] drm/probe-helper: Create a HPD IRQ event helper for a
single connector
The drm_helper_hpd_irq_event() function is iterating over all the
connectors when an hotplug event is detected.
During that iteration, it will call each connector detect function and
figure out if its status changed.
Finally, if any connector changed, it will notify the user-space and the
clients that something changed on the DRM device.
This is supposed to be used for drivers that don't have a hotplug
interrupt for individual connectors. However, drivers that can use an
interrupt for a single connector are left in the dust and can either
reimplement the logic used during the iteration for each connector or
use that helper and iterate over all connectors all the time.
Since both are suboptimal, let's create a helper that will only perform
the status detection on a single connector.
Signed-off-by: Maxime Ripard <maxime@cerno.tech>
---
Changes from v1:
- Rename the shared function
- Move the hotplug event notification out of the shared function
- Added missing locks
- Improve the documentation
- Switched to drm_dbg_kms

Date: Thu, 19 Aug 2021 13:50:12 +0200
Subject: [PATCH] drm/vc4: hdmi: Actually check for the connector
status in hotplug
The drm_helper_hpd_irq_event() documentation states that this function
is "useful for drivers which can't or don't track hotplug interrupts for
each connector." and that "Drivers which support hotplug interrupts for
each connector individually and which have a more fine-grained detect
logic should bypass this code and directly call
drm_kms_helper_hotplug_event()". This is thus what we ended-up doing.
However, what this actually means, and is further explained in the
drm_kms_helper_hotplug_event() documentation, is that
drm_kms_helper_hotplug_event() should be called by drivers that can
track the connection status change, and if it has changed we should call
that function.
This underlying expectation we failed to provide is that the caller of
drm_kms_helper_hotplug_event() should call drm_helper_probe_detect() to
probe the new status of the connector.
Since we didn't do it, it meant that even though we were sending the
notification to user-space and the DRM clients that something changed we
never probed or updated our internal connector status ourselves.
This went mostly unnoticed since the detect callback usually doesn't
have any side-effect. Also, if we were using the DRM fbdev emulation
(which is a DRM client), or any user-space application that can deal
with hotplug events, chances are they would react to the hotplug event
by probing the connector status eventually.
However, now that we have to enable the scrambler in detect() if it was
enabled it has a side effect, and an application such as Kodi or
modetest doesn't deal with hotplug events. This resulted with a black
screen when Kodi or modetest was running when a screen was disconnected
and then reconnected, or switched off and on.

Subject: [PATCH] amba_pl011: Don't use DT aliases for numbering
The pl011 driver looks for DT aliases of the form "serial<n>",
and if found uses <n> as the device ID. This can cause
/dev/ttyAMA0 to become /dev/ttyAMA1, which is confusing if the
other serial port is provided by the 8250 driver which doesn't
use the same logic.

Subject: [PATCH] amba_pl011: Round input clock up
The UART clock is initialised to be as close to the requested
frequency as possible without exceeding it. Now that there is a
clock manager that returns the actual frequencies, an expected
48MHz clock is reported as 47999625. If the requested baudrate
== requested clock/16, there is no headroom and the slight
reduction in actual clock rate results in failure.
Detect cases where it looks like a "round" clock was chosen and
adjust the reported clock to match that "round" value. As the
code comment says:
/*
* If increasing a clock by less than 0.1% changes it
* from ..999.. to ..000.., round up.

From 784d9bd9e4fecb27ceb3a0d0375dc13d1f35e44c Mon Sep 17 00:00:00 2001
From: Harm Hanemaaijer <fgenfb@yahoo.com>
Date: Thu, 20 Jun 2013 20:21:39 +0200
Subject: [PATCH] Speed up console framebuffer imageblit function
Especially on platforms with a slower CPU but a relatively high
framebuffer fill bandwidth, like current ARM devices, the existing
console monochrome imageblit function used to draw console text is
suboptimal for common pixel depths such as 16bpp and 32bpp. The existing
code is quite general and can deal with several pixel depths. By creating
special case functions for 16bpp and 32bpp, by far the most common pixel
formats used on modern systems, a significant speed-up is attained
which can be readily felt on ARM-based devices like the Raspberry Pi
and the Allwinner platform, but should help any platform using the
fb layer.
The special case functions allow constant folding, eliminating a number
of instructions including divide operations, and allow the use of an
unrolled loop, eliminating instructions with a variable shift size,
reducing source memory access instructions, and eliminating excessive
branching. These unrolled loops also allow much better code optimization
by the C compiler. The code that selects which optimized variant is used
is also simplified, eliminating integer divide instructions.
The speed-up, measured by timing 'cat file.txt' in the console, varies
between 40% and 70%, when testing on the Raspberry Pi and Allwinner
ARM-based platforms, depending on font size and the pixel depth, with
the greater benefit for 32bpp.

Subject: [PATCH] of: configfs: Use of_overlay_fdt_apply API call
The published API to the dynamic overlay application mechanism now
takes a Flattened Device Tree blob as input so that it can manage the
lifetime of the unflattened tree. Conveniently, the new API call -
of_overlay_fdt_apply - is virtually a drop-in replacement for
create_overlay, which can now be deleted.

Subject: [PATCH] media: tc358743: fix connected/active CSI-2 lane
reporting
g_mbus_config was supposed to indicate all supported lane numbers, not
only the number of those currently in active use. Since the TC358743
can dynamically reduce the number of active lanes if the required
bandwidth allows for it, report all lane numbers up to the connected
number of lanes as supported in pdata mode.
In device tree mode, do not report lane count and clock mode at all, as
the receiver driver can determine these from the device tree.
To allow communicating the number of currently active lanes, add a new
bitfield to the v4l2_mbus_config flags. This is a temporary fix, to be
used only until a better solution is found.

Subject: [PATCH] soc: bcm: bcm2835-pm: Add support for 2711.
Without the actual power management part any more, there's a lot less
to set up for V3D. We just need to clear the RSTN field for the power
domain, and expose the reset controller for toggling it again.
This is definitely incomplete -- the old ISP and H264 is in the old
bridge, but since we have no consumers of it I've just done the
minimum to get V3D working.

+* Sony 1/4.0-Inch 8Mpixel CMOS Digital Image Sensor
+
+The Sony imx219 is a 1/4.0-inch CMOS active pixel digital image sensor with
+an active array size of 3280H x 2464V. It is programmable through I2C
+interface. The I2C address is fixed to 0x10 as per sensor data sheet.
+Image data is sent through MIPI CSI-2, which is configured as either 2 or 4
+data lanes.
+
+Required Properties:
+- compatible: value should be "sony,imx219" for imx219 sensor
+- reg: I2C bus address of the device
+- clocks: reference to the xclk input clock.
+- clock-names: should be "xclk".
+- DOVDD-supply: Digital I/O voltage supply, 1.8 volts
+- AVDD-supply: Analog voltage supply, 2.8 volts
+- DVDD-supply: Digital core voltage supply, 1.2 volts
+
+Optional Properties:
+- xclr-gpios: reference to the GPIO connected to the xclr pin, if any. Must be
+ released after all supplies are applied.
+ This is an active high signal to the imx219.
+
+The imx219 device node should contain one 'port' child node with
+an 'endpoint' subnode. For further reading on port node refer to
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Endpoint node required properties for CSI-2 connection are:
+- remote-endpoint: a phandle to the bus receiver's endpoint node.
+- clock-lanes: should be set to <0> (clock lane on hardware lane 0)
+- data-lanes: should be set to <1 2>, or <1 2 3 4> (two or four lane CSI-2
+ supported)
+
+Example:
+ sensor@10 {
+ compatible = "sony,imx219";
+ reg = <0x10>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ clocks = <&imx219_clk>;
+ clock-names = "xclk";
+ xclr-gpios = <&gpio_sensor 0 0>;
+ DOVDD-supply = <&vgen4_reg>; /* 1.8v */
+ AVDD-supply = <&vgen3_reg>; /* 2.8v */
+ DVDD-supply = <&vgen2_reg>; /* 1.2v */
+
+ imx219_clk: camera-clk {
+ compatible = "fixed-clock";
+ #clock-cells = <0>;
+ clock-frequency = <24000000>;
+ };
+
+ port {
+ sensor_out: endpoint {
+ remote-endpoint = <&csiss_in>;
+ clock-lanes = <0>;
+ data-lanes = <1 2>;
+ };
+ };
+ };

Subject: [PATCH] Rename HDMI ALSA device names, check for enable state
HDMI Alsa devices renamed to match names used by DRM, to
HDMI 1 and HDMI 2
Check for which HDMI devices are connected and only create
devices for those that are present.
The rename of the devices might cause some backwards compatibility
issues, but since this particular part of the driver needs to be
specifically enabled, I suspect the number of people who will see
the problem will be very small.

Subject: [PATCH] media: uapi: hevc: Add segment address field
From https://patchwork.linuxtv.org/patch/60725/
Changes requested, but mainly docs.
If HEVC frame consists of multiple slices, segment address has to be
known in order to properly decode it.
Add segment address field to slice parameters.

If no buffer has been queued by a userland application, we use an
internal dummy buffer for the hardware to spin in. This will allow
the driver to release the existing userland buffer back to the
application for processing.

on metadata node
The unicam driver supports both the SOURCE_CHANGE and CTRL events. Both
events are only generated on the image video node, so the event-related
ioctls are useless on the medatada node. Disable them.

unicam_release
unicam_release calls _vb2_fop_release, which will call stop_streaming
if that particular node was streaming. Calling it unconditionally (as
the code was) means that if a second handle was opened eg to alter
a setting, on closing that connection it also stopped Unicam.

Subject: [PATCH] media: bcm2835-unicam: Always service interrupts
From when bringing up the driver, there was a check in the isr
to ignore interrupts (claiming them handled) should the driver
not be streaming.
The VPU now will not register a camera driver if it finds a
CSI2 node enabled in device tree, therefore this flawed check is
redundant.

Subject: [PATCH] sc16is7xx: Fix for hardware flow control
The SC16IS7XX hardware flow control is mishandled by the driver in
a number of ways:
1. The set_baud method accidentally clears it when setting EFR bit.
2. Even though hardware flow control is enabled, it isn't indicated
back to the serial framework.
3. Applying the flow control clears the EFR bit.
4. The CTS support is not indicated in the return from
sc16is7xx_get_mctrl.
Address all of those issues using a mixture of patches found on the
linked pages.

Subject: [PATCH] media: bcm2835-unicam: change minimum number of
vb2_queue buffers to 1
Since the unicam driver was modified to write to a dummy buffer when no
user-supplied buffer is available, it can now write to and return a
buffer even when there's only a single one. Enable this by changing the
min_buffers_needed in the vb2_queue; it will be useful for enabling
still captures without allocating more memory than absolutely necessary.

Subject: [PATCH] snd_bcm2835: disable HDMI audio when vc4 is used
(#3640)
Things don't work too well when both the vc4 driver and the firmware
driver are trying to control the same audio output:
[ 763.569406] bcm2835_audio bcm2835_audio: vchi message timeout, msg=5
Hence, when the vc4 HDMI driver is used, let it control audio. This is done
by introducing a new device tree property to the audio node, and
extending the vc4-kms-v3d overlays to set it appropriately.

Subject: [PATCH] staging: bcm2835-audio: Add missing MODULE_ALIAS
Commit 8353fe6f1e0f ("Revert "staging: bcm2835-audio: Drop DT
dependency"") reverts the upstream change and makes bcm2835-audio use
device tree again, however, it also removes the MODULE_ALIAS for the
platform device. This MODULE_ALIAS is needed, because VCHIQ registers
bcm2835-audio as a child platform device since commit 25c7597af20d
("staging: vchiq_arm: Register a platform device for audio"), and this
mechanism is adopted also in the downstream kernel.
This commit puts back that MODULE_ALIAS to make bcm2835-audio
autoprobing work again. The rest of VCHIQ children have their
MODULE_ALIASes in place.

Subject: [PATCH] media: i2c: imx290: set the format before
VIDIOC_SUBDEV_G_FMT is called
Commit d46cfdc86c30d5ec768924f0b1e2683c8d20b671 upstream.
With the current driver 'media-ctl -p' issued right after the imx290 driver
is loaded prints:
pad0: Source
[fmt:unknown/0x0]
The format value of zero is due to the current_format field of the imx290
struct not being initialized yet.
As imx290_entity_init_cfg() calls imx290_set_fmt(), the current_mode field
is also initialized, so the line which set current_mode to a default value
in driver's probe() function is no longer needed.

Subject: [PATCH] media: i2c: imx290: Correct range for V4L2_CID_GAIN
to 0-238
The datasheet lists the gain as being 0.0 to 72.0dB in 0.3dB steps, which
makes 238 steps total.
Correct the 0-72 range defined in the driver.

Subject: [PATCH] media: i2c: imx290: Add support for V4L2_CID_VBLANK
In order to calculate framerate and durations userspace needs
the vertical blanking information. This can be configurable,
and indeed the datasheet lists different values for VBLANK for
the 1080p and 720p modes.
Add the new control, and adopt the datasheet values for each mode.
