2017-09-05mfd: axp20x: Add support for AXP813 PMICChen-Yu Tsai
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.

2017-04-27mfd: axp20x: Support AXP803 variantIcenowy Zheng
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. Signed-off-by: Icenowy Zheng <icenowy@aosc.io> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2016-09-13mfd: axp20x: Add support for AXP806 PMICChen-Yu Tsai
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.

2016-04-19mfd: axp20x: Add support for AXP809 PMICChen-Yu Tsai
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.

2016-02-12mfd: axp20x: Add support for RSB based AXP223 PMICChen-Yu Tsai
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. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
