Icenowy Zheng 1578353e05 mfd: axp20x: Support AXP803 variant
AXP803 is a new PMIC chip produced by X-Powers, usually paired with A64
via RSB bus. The PMIC itself is like AXP288, but with RSB support and
dedicated VBUS and ACIN.

Add support for it in the axp20x mfd driver.

Currently only power key function is supported.

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 20147f0d4f mfd: axp20x: Add support for AXP809 PMIC
The X-Powers AXP809 is a new PMIC that is paired with Allwinner's A80
SoC, along with a slave AXP806 PMIC.

This PMIC is quite similar to the earlier AXP223, though the interrupts
and regulator have changed a bit.

This patch adds support for the interrupts and power button of the PMIC.

Chen-Yu Tsai 02071f0f79 mfd: axp20x: Add support for RSB based AXP223 PMIC
The AXP223 is a new PMIC commonly paired with Allwinner A23/A33 SoCs.
It is functionally identical to AXP221; only the regulator default
voltage/status and the external host interface are different.
