Installation:
The installation must be done via TFTP by disassembling the router.
On other occasions Cudy has distributed intermediate firmware to make
installation easier, and so I recommend checking the Wiki for this
device if there is a more convenient solution than the one below.
To install using TFTP:
1. Connect to UART.
2. With the router off, press the RESET button. While the router is turning
on, the button should continue to be pressed for at least 5 seconds.
3. A u-boot shell will automatically open.
4. Connect to LAN and set your IP to 192.168.1.88/24. Configure a
TFTP server and an OpenWrt initramfs-kernel.bin firmware file.
5. Run these steps in u-boot using the name of your file.
setenv bootfile initramfs-kernel.bin
tftpboot
bootm
6. If you can reach LuCI or SSH now, just use the sysupgrade image
with the 'Keep settings' option turned off.

The clocks for SPI busses were named wrongly which resulted in the
spi-mt65xx driver not requesting them. This has apparently been
worked around by marking the clocks required for SPI0 which is used
for SPI-NOR and SPI-NAND flash chips as critical.
Fix the device tree for all 3 generic SPI host controllers and no
longer mark clocks as critical.

Assign pwm function of PWM0 pin to the pwm-fan.
This is mostly just cosmetics as it basically reflects the default
setting of that pin.

Add additionals possible pinctrl group for pwm2~7 on pins
pin 4 (GPIO_A) pwm7
pin 58 (JTAG_JTDI) pwm2
pin 59 (JTAG_JTDO) pwm3
pin 60 (JTAG_JTMS) pwm4
pin 61 (JTAG_JTCLK) pwm5
pin 62 (JTAG_JTRST_N) pwm6
They can be useful e.g. on the BPi-R4 as in that way pwm2~6 can be exposed
on the 26-pin header (pwm6 always, pwm2~5 instead of the full UART).

Use pending patchset for 2.5GE PHY driver, unifying LED handling

Backport newly introduced support for 'active-high' property and use
it to correctly implement polarity assignment for Aquantia PHY LEDs.
Previously the 'active-low' property was used to switch a LED PIN to
active-high ("drive VDD" in Aquantia-speak) mode.
