From e0f8ad2a705367518b5c56bf9d6da89681467c02 Mon Sep 17 00:00:00 2001

Subject: [PATCH] mfd: axp20x: Add support for AXP15060 PMIC
The AXP15060 is a PMIC chip produced by X-Powers, and could be connected
via an I2C bus.
Describe the regmap and the MFD bits, along with the registers exposed
via I2C. Eventually advertise the device using a new compatible string
and add support for power off the system.
The driver would disable PEK function if IRQ is not configured in device
tree, since some boards (For example, Starfive Visionfive 2) didn't
connect IRQ line of PMIC to SOC.
GPIO function isn't enabled in this commit, since its configuration
operation is different from any existing AXP PMICs and needs
logic modification on existing driver. GPIO support might come in later
patches.

From 9e72869d0fe12aba8cd489e485d93912b3f5c248 Mon Sep 17 00:00:00 2001

Subject: [PATCH] regulator: axp20x: Add AXP15060 support
The AXP15060 is a typical I2C-controlled PMIC, seen on multiple boards
with different default register value. Current driver is tested on
Starfive Visionfive 2.
The RTCLDO is fixed, and cannot even be turned on or off. On top of
that, its voltage is customisable (either 1.8V or 3.3V). We pretend it's
a fixed 1.8V regulator since other AXP driver also do like this. Also,
BSP code ignores this regulator and it's not used according to VF2
schematic.
Describe the AXP15060's voltage settings and switch registers, how the
voltages are encoded, and connect this to the MFD device via its
regulator ID.

From 63eeabbc9dbddd7381409feccd9082e5ffabfe59 Mon Sep 17 00:00:00 2001
From: Aidan MacDonald <aidanmacdonald.0x0@gmail.com>

Subject: [PATCH] mfd: axp20x: Add support for AXP192
The AXP192 PMIC is similar to the AXP202/AXP209, but with different
regulators, additional GPIOs, and a different IRQ register layout.
