The AXP813 PMIC is relatively close to the already supported AXP20X and AXP22X. It provides three different power outputs: battery, AC and USB, and measures a few different things: temperature, power supply status, current current and voltage supplied, maximum current limit, battery capacity, min and max voltage limits. One of its two GPIOs can be used as an ADC. There are a few differences with AXP20X/AXP22X PMICs though: - a different constant charge current formula, - battery temperature, GPIO0 and battery voltages are the only voltages measurable, - all data are stored on 12 bits (AXP20X/AXP22X had one type of data that was stored on 13 bits), - different scales and offsets, - a different ADC rate formula and register, This patch series adds support for the PMIC's ADC and battery power supply in the existing drivers. Make the axp20x MFD automatically probe the ADC driver, add the battery power supply node in axp81x node and enable it for the TBS A711 since it has a soldered battery. Q: The BananaPi M3 has two solder balls for battery, should the battery power supply node be enabled for this board as well?
