Chen-Yu Tsai 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.

Quentin Schulz 1a3f675564 iio: adc: axp20x_adc: add support for AXP813 ADC
The X-Powers AXP813 PMIC is really close to what is already done for
AXP20X/AXP22X.

There are two pairs of bits to set the rate (one for Voltage and Current
measurements and one for TS/GPIO0 voltage measurements) instead of one.

The register to set the ADC rates is different from the one for
AXP20X/AXP22X.

GPIO0 can be used as an ADC (measuring Volts) unlike for AXP22X.

The scales to apply to the different inputs are unlike the ones from
AXP20X and AXP22X.

Chen-Yu Tsai d81851c176 regulator: axp20x: Add support for AXP813 regulators
The AXP813 PMIC has 7 DC-DC buck regulators, 16 LDOs (including the
fixed RTC LDO and 2 GPIO LDOs), and 1 switchable. The drive-vbus
feature is also supported. All the hardware details are very similar
to the AXP803, with the following exceptions:

  - Extra DCDC7 buck regulator, with the same range as DCDC6

  - SWitch now has a separate supply pin, instead of being chained
    internaly from DCDC1

  - RTC LDO output voltage is now 1.8V

  - FLDO3 is an LDO with switchable supplies, but unconfigurable output
    voltage. The voltage is always half that of its supply.

Support for FLDO3 is currently unimplemented, as it requires runtime
switching of its supplies, something the regulator subsystem does not
support. It is not used in either the reference designs nor actually
produced boards available.

Chen-Yu Tsai 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.

The interrupt line of the entire family of axp2xx pmics is active-low,
for devicetree enumerated irqs, this is dealt with in the devicetree.

ACPI irq resources have a flag field for this too, I tried using this
on my CUBE iwork8 Air tablet, but it does not contain the right data.

The dstd shows the irq listed as either ActiveLow or ActiveHigh,
depending on the OSID variable, which seems to be set by the
"OS IMAGE ID" in the BIOS/EFI setup screen.

Since the acpi-resource info is no good, simply pass in IRQF_TRIGGER_LOW
on the axp288.

Together with the other axp288 fixes in this series, this fixes the axp288
irq contineously triggering.

Hans de Goede 888f97435a power: supply: axp288_fuel_gauge: Drop platform_data dependency
When the axp288_faul_gauge driver was originally merged, it was
merged with a dependency on some other driver providing platform
data for it.

However the battery-data-framework which should provide that data
never got merged, resulting in x86 tablets / laptops with an axp288
having no working battery monitor, as before this commit the driver
would simply return -ENODEV if there is no platform data.

This commit removes the dependency on the platform_data instead
checking that the firmware has initialized the fuel-gauge and
reading the info back from the pmic.

What is missing from the read-back info is the table to map raw adc
values to temperature, so this commit drops the temperature and
temperature limits properties. The min voltage, charge design and
model name info is also missing. Note that none of these are really
important for userspace to have.

All other functionality is preserved and actually made available
by this commit.

Chen-Yu Tsai 34d9030b5d mfd: axp20x: Add address extension registers for AXP806 regmap
The AXP806 supports either master/standalone or slave mode.
Slave mode allows sharing the serial bus, even with multiple
AXP806 which all have the same hardware address.

This is done with extra "serial interface address extension",
or AXP806_BUS_ADDR_EXT, and "register address extension", or
AXP806_REG_ADDR_EXT, registers. The former is read-only, with
1 bit customizable at the factory, and 1 bit depending on the
state of an external pin. The latter is writable. Only when
the these device addressing bits (in the upper 4 bits of the
registers) match, will the device respond to operations on
its other registers.

Add these 2 registers to the regmap so we can access them.

Chen-Yu Tsai 8824ee8573 mfd: axp20x: Add support for AXP806 PMIC
The X-Powers AXP806 is a new PMIC that is paired with Allwinner's A80
SoC, along with a master AXP809 PMIC.

This PMIC has a new register layout, and supports some functions not
seen in other X-Powers PMICs, such as master-slave mode, or having
multiple AXP806 PMICs on the same bus with address space extension,
or supporting both I2C and RSB mode. I2C has not been tested.

This patch adds support for the interrupts of the PMIC. A regulator
sub-device is enabled, but actual regulator support will come in a
later patch.

Chen-Yu Tsai 4fd4115142 mfd: axp20x: Split the driver into core and i2c bits
The axp20x driver assumes the device is i2c based. This is not the
case with later chips, which use a proprietary 2 wire serial bus
by Allwinner called "Reduced Serial Bus".

This patch follows the example of mfd/wm831x and splits it into
an interface independent core, and an i2c specific glue layer.
MFD_AXP20X and the new MFD_AXP20X_I2C are changed to tristate
symbols, allowing the driver to be built as modules.

Whitespace and other style errors in the moved i2c specific code
have been fixed. Included but unused header files are removed as
well.

Hans de Goede 69fb4dcada power: Add an axp20x-usb-power driver
This adds a driver for the usb power_supply bits of the axp20x PMICs.

I initially started writing my own driver, before coming aware of
Bruno Prémont's excellent earlier RFC with a driver for this.

My driver was lacking CURRENT_MAX and VOLTAGE_MIN support Bruno's
drvier has, so I've copied the code for those from his driver.

Note that the AC-power-supply and battery charger bits will need separate
drivers. Each one needs its own devictree child-node so that other
devicetree nodes can reference the right power-supply, and thus each one
will get its own mfd-cell / platform_device and platform-driver.

Boris BREZILLON f05be589ff mfd: axp20x: Add AXP22x PMIC support
Add support for the AXP22x PMIC devices to the existing AXP20x driver.
This includes the AXP221 and AXP223, which are identical except for
the external data bus. Only AXP221 is added for now. AXP223 will be
added after it's Reduced Serial Bus (RSB) interface is supported.

AXP22x defines a new set of registers, power supplies and regulators,
but most of the API is similar to the AXP20x ones.

A new irq chip definition is used, even though the available interrupts
on AXP22x is a subset of those on AXP20x. This is done so the interrupt
numbers match those on the datasheet.

This patch only enables the interrupts, system power-off function, and PEK
sub-device. The regulator driver must first support different variants
before we enable it from the mfd driver.
