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. v2: - introduce data structure instead of ID for variant specific code in battery driver, - add DT binding for ADC driver, - make mfd probe the ADC driver via DT as well so that its IIO channels can be consumed by other drivers via DT mapping, Thanks, Quentin Quentin Schulz (16): iio: adc: axp20x_adc: put ADC rate setting in a per-variant function dt-bindings: iio: adc: add binding for X-Powers AXP PMICs ADC iio: adc: axp20x_adc: make it possible to probe from DT ARM: dtsi: axp209: add node for ADC ARM: dtsi: axp22x: add node for ADC mfd: axp20x: make AXP209/22x cells probe their ADC via DT dt-bindings: iio: adc: axp20x_adc: add AXP813 variant iio: adc: axp20x_adc: add support for AXP813 ADC ARM: dtsi: axp81x: add node for ADC mfd: axp20x: probe axp20x_adc driver for AXP813 power: supply: axp20x_battery: use data structure instead of ID for variant specific code dt-bindings: power: supply: axp20x: add AXP813 battery DT binding power: supply: axp20x_battery: add support for AXP813 mfd: axp20x: add battery power supply cell for AXP813 ARM: dtsi: axp81x: add battery power supply subnode ARM: dtsi: sun8i: a711: enable battery power supply subnode Documentation/devicetree/bindings/iio/adc/axp20x_adc.txt | 48 ++++++++++++++++++++++- Documentation/devicetree/bindings/power/supply/axp20x_battery.txt | 8 ++-- arch/arm/boot/dts/axp209.dtsi | 5 ++- arch/arm/boot/dts/axp22x.dtsi | 5 ++- arch/arm/boot/dts/axp81x.dtsi | 10 +++++- arch/arm/boot/dts/sun8i-a83t-tbs-a711.dts | 4 ++- drivers/iio/adc/axp20x_adc.c | 160 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++---- drivers/mfd/axp20x.c | 13 +++++- drivers/power/supply/axp20x_battery.c | 134 ++++++++++++++++++++++++++++++++++++++++++++++-------------- include/linux/mfd/axp20x.h | 2 +- 10 files changed, 345 insertions(+), 44 deletions(-) create mode 100644 Documentation/devicetree/bindings/iio/adc/axp20x_adc.txt base-commit: 895c0dde398510a5b5ded60e5064c11b94bd30ca -- git-series 0.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
