68f860426d mfd: axp20x: AXP717: Fix missing IRQ status registers range
While we list the "IRQ status *and acknowledge*" registers as volatile
in the MFD description, they are missing from the writable range array,
so acknowledging any interrupts was met with an -EIO error.
This error propagates up, leading to the whole AXP717 driver failing to
probe, which is fatal to most systems using this PMIC, since most
peripherals refer one of the PMIC voltage rails.
This wasn't noticed on the initial submission, since the interrupt was
completely missing at this point, but the DTs now merged describe the
interrupt, creating the problem.

Add the five registers that hold those bits to the writable array.

This fixes the boot on the Anbernic systems using the AXP717 PMIC.

The AXP717a is a PMIC chip produced by X-Powers, it can be connected to
an I2C or RSB bus.

It's a rather complete PMIC, with many regulators, interrupts, an ADC and
battery charging functionality. It also offer USB type-C CC pin
handling.

Describe the regmap and the MFD bits, along with the registers exposed
via I2C or RSB. This covers the regulator, interrupts and power key
devices for now.

b2cb2ae222 mfd: axp20x: Generalise handling without interrupt
At the moment we allow the AXP15060 and the AXP806 PMICs to omit the
interrupt line to the SoC, and we skip registering the PEK (power key)
driver in this case, since that crashes when no IRQ is described in the
DT node.
The IRQ pin potentially not being connected to anything does affect more
PMICs, though, and the PEK driver is not the only one requiring an
interrupt: at least the AC power supply driver crashes in a similar
fashion.

Generalise the handling of AXP MFD devices when the platform tables
describe no interrupt, by allowing each device to specify an alternative
MFD list for this case. If no specific alternative is specified, we go
with the safe default of "just the regulators", which matches the current
situation.

This enables new devices using the AXP313a PMIC, but not connecting the
IRQ pin.

more appropriate for modern systems than those made by the rbtree cache. In

there.

75c8cb2f4c 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.

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

32679a7a6b mfd: axp20x: Add supplied-from property to axp288_fuel_gauge cell
The power-supply framework has the notion of one power-supply device
being supplied by another. A typical example of this is a charger
charging a battery.

A tablet getting plugged in to charge (or plugged out) only results in
events seen by the axp288_charger device / MFD cell. Which means that
a change udev-event only gets send for the charger power-supply class
device, not for the battery (the axp288_fuel_gauge device).

The axp288_fuel_gauge does have an external_power_change'd callback
which will generate a change udev-event when called. But before this
commit this never got called because the power-supply core only calls
this when a power-supply class device's supplier changes and the
supplier link from axp288_charger to axp288_fuel_gauge was missing.

Add a "supplied-from" property to axp288_fuel_gauge cell, pointing
to the "axp288_charger" power-supply class device, so that the
axp288_fuel_gauge's external_power_change'd callback gets called on
axp288_charger state changes.

f949a9ebce mfd: axp20x: Update AXP288 volatile ranges
On Cherry Trail devices with an AXP288 PMIC the external SD-card slot
used the AXP's DLDO2 as card-voltage and either DLDO3 or GPIO1LDO
(GPIO1 pin in low noise LDO mode) as signal-voltage.

These regulators are turned on/off and in case of the signal-voltage
also have their output-voltage changed by the _PS0 and _PS3 power-
management ACPI methods on the MMC-controllers ACPI fwnode as well as
by the _DSM ACPI method for changing the signal voltage.

The AML code implementing these methods is directly accessing the
PMIC through ACPI I2C OpRegion accesses, instead of using the special
PMIC OpRegion handled by drivers/acpi/pmic/intel_pmic_xpower.c .

This means that the contents of the involved PMIC registers can change
without the change being made through the regmap interface, so regmap
should not cache the contents of these registers.

Mark the regulator power on/off, the regulator voltage control and the
GPIO1 control registers as volatile, to avoid regmap caching them.

Specifically this fixes an issue on some models where the i915 driver
toggles another LDO using the same on/off register on/off through
MIPI sequences (through intel_soc_pmic_exec_mipi_pmic_seq_element())
which then writes back a cached on/off register-value where the
card-voltage is off causing the external sdcard slot to stop working
when the screen goes blank, or comes back on again.

The regulator register-range now marked volatile also includes the
buck regulator control registers. This is done on purpose these are
normally not touched by the AML code, but they are updated directly
by the SoC's PUNIT which means that they may also change without going
through regmap.

Note the AXP288 PMIC is only used on Bay- and Cherry-Trail platforms,
so even though this is an ACPI specific problem there is no need to
make the new volatile ranges conditional since these platforms always
use ACPI.

3efc465f91 mfd: axp20x: Allow AXP 806 chips without interrupt lines
Currently the AXP chip requires to have its IRQ line connected to some
interrupt controller, and will fail probing when this is not the case.

On a new Allwinner SoC (H616) there is no NMI pin anymore, and at
least one board does not connect the AXP's IRQ pin to anything else,
so the interrupt functionality of the AXP chip is simply not available.

Check whether the interrupt line number returned by the platform code is
valid, before trying to register the irqchip. If not, we skip this
registration, to avoid the driver to bail out completely.
Also we need to skip the power key functionality, as this relies on
a valid IRQ as well.

We need to set the register as volatile to prevent regmap from caching

753a8d083e mfd: axp20x: Re-align MFD cell entries
In the axp20x driver, the various mfd_cell lists had varying amounts
of indentation, sometimes even within the same list. For the axp288,
there's no alignment at all.

Re-align the right hand side of the assignments with the least amount
of tabs possible. Also collapse the closing bracket and the opening
bracket of the next entry onto the same line for the axp288, to be
consistent with all the other mfd_cell lists.

This patch is whitespace change only. No functionality is modified.

06f4901092 mfd: axp20x: Add self-working mode support for AXP806
The AXP806 can operate in a standalone "self-working" mode, in which it
is also responsible for power control of the overall system. This mode
is similar to the master mode, but the EN/PWRON pin functions as a power
button, instead of a level-triggered enable switch.

This patch adds code checking for the new "x-powers,self-working-mode"
property, and a separate mfd_cell list that includes the power button
(PEK) sub-device.

eef2b53a3e mfd: axp20x: Correct AXP806 POK interrupt prefix
When AXP806 support was added, POK was incorrectly expanded to PWROK.
However, the datasheet lists them as POK[LSNP], which is the same as
on the AXP288. Furthermore, the registers associated with POK functions
are the same as the PEK on the other AXP PMICs. This suggests that
"POK" means "Power On Key", much like "PEK" means "Power Enable Key",
instead of "Power OK".

This patch changes the "PWROK" prefix to "POK" for these interrupts.

7303733a6c mfd: axp20x: Add support for AXP813 PMIC
The X-Powers AXP813 PMIC is normally used with Allwinner's A83T SoC.
It has the same range of functions as other X-Powers PMICs, such as
DC-DC buck converter and linear regulator outputs, AC-IN and VBUS
power supplies, power button trigger, GPIOs, ADCs, and a battery
charger.

Note that the IRQ table given in the datasheet is incorrect: in IRQ
enable/status registers 1, there are separate IRQs for ACIN and VBUS,
instead of bits [7:5] being the same as bits [4:2]. So it shares the
same IRQs as the AXP803, rather than the AXP288.

This patch adds basic mfd support for it, with only the power button
enabled.

commit b101829a029a ("mfd: axp20x: Fix AXP806 access errors on cold boot")
was intended to fix the case where a board uses an AXP806 in slave mode,
but the boot loader leaves it in master mode for lack of AXP806 support.
But now the driver breaks on boards where the PMIC is operating in master
mode. This patch lets the driver use the new device tree property
"xpowers,master-mode" to set the correct operating mode for the board.
