generic: 6.1: backport AXP PMIC support

Browse Source 
Backport AXP15060, AXP313a and AXP192 support.
The AXP15060 PMIC is used for starfive boards,
and the AXP313a PMIC is used for sunxi boards.
Remove conflicting patches from starfive target.

Subject: [PATCH] mfd: axp20x: Fix order of pek rise and fall events
The power button can get "stuck" if the rising edge and falling edge irq
are read in the same pass. This can often be triggered when resuming
from suspend if the power button is released before the kernel handles
the interrupt.
Swapping the order of the rise and fall events makes sure that the press
event is handled first, which prevents this situation.

Subject: [PATCH] mfd: axp20x: Switch to the sys-off handler API
This removes a layer of indirection through pm_power_off() and allows
the PMIC handler to be used as a fallback when firmware power off fails.
This happens on boards like the Clockwork DevTerm R-01 where OpenSBI
does not know how to use the PMIC to power off the board.
Move the check for AXP288 to avoid registering a dummy handler.

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.

Subject: [PATCH] mfd: axp20x: Add support for AXP313a PMIC
The AXP313a is a PMIC chip produced by X-Powers, it can be connected via
an I2C bus.
The name AXP1530 seems to appear as well, and this is what is used in
the BSP driver. From all we know it's the same chip, just a different
name. However we have only seen AXP313a chips in the wild, so go with
this name.
Compared to the other AXP PMICs it's a rather simple affair: just three
DCDC converters, three LDOs, and no battery charging support.
Describe the regmap and the MFD bits, along with the registers exposed
via I2C. Aside from the various regulators, also describe the power key
interrupts, and adjust the shutdown handler routine to use a different
register than the other PMICs.
Eventually advertise the device using the new compatible string.

From 60fd7eb89670d2636ac3156881acbd103c6eba6a Mon Sep 17 00:00:00 2001

Subject: [PATCH] regulator: axp20x: Add support for AXP313a variant
The AXP313a is your typical I2C controlled PMIC, although in a lighter
fashion compared to the other X-Powers PMICs: it has only three DCDC
rails, three LDOs, and no battery charging support.
The AXP313a datasheet does not describe a register to change the DCDC
switching frequency, and talks of it being fixed at 3 MHz. Check that
the property allowing to change that frequency is absent from the DT,
and bail out otherwise.
The third LDO, RTCLDO, is fixed, and cannot even be turned on or off,
programmatically. On top of that, its voltage is customisable (either
1.8V or 3.3V), which we cannot describe easily using the existing
regulator wrapper functions. This should be fixed properly, using
regulator-{min,max}-microvolt in the DT, but this requires more changes
to the code. As some other PMICs (AXP2xx, AXP803) seem to paper over the
same problem as well, we follow suit here and pretend it's a fixed 1.8V
regulator. A proper fix can follow later. The BSP code seems to ignore
this regulator altogether.
Describe the AXP313A's voltage settings and switch registers, how the
voltages are encoded, and connect this to the MFD device via its
regulator ID.

Subject: [PATCH 118/122] driver: regulator: axp20x: Support AXP15060 variant.

Subject: [PATCH] regulator: axp20x: Add AXP15060 support
Add axp15060 variant support to axp20x
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.
Signed-off-by: ziv.xu <ziv.xu@starfive.com>
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.

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.
