Raw Message
The binding already lists compatibles and regulators for the AXP806,
but it is missing from the list of supported chips at the beginning.

Add it.

The X-Powers AXP813 is a PMIC designed to be paired with Allwinner's
A83T SoC. There is also an AXP818, which is paired with the H8 SoC.

The two models seem to be identical, apart from the external markings.

This patch introduces the basic mfd and regulator bindings for the
AXP813.

The A83T has an RSB controller for talking to the PMIC and audio codec.
Add a device node for it. Since there is only one usable pinmux setting,
for it, add that as well.

Raw Message
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 AXP813/AXP818 PMICs used with the A83T/H8 SoCs are actually 2 dies
in one package sharing the serial bus (I2C/RSB) pins. One die is the
actual PMIC. The other is an AC100 codec / RTC combo chip.

This patch enables the RSB controller and adds the device nodes for
the AC100 chip under it.

Raw Message
The AXP813/AXP818 PMICs used with the A83T/H8 SoCs are actually 2 dies
in one package sharing the serial bus (I2C/RSB) pins. One die is the
actual PMIC. The other is an AC100 codec / RTC combo chip.

This patch adds a device node for the PMIC die.

The binding already lists compatibles and regulators for the AXP806,
but it is missing from the list of supported chips at the beginning.
Add it.
Fixes: 204ae2963e10 ("mfd: axp20x: Add bindings for AXP806 PMIC")
