This patch adds the DT binding documentation for the battery power supply which gets various data from the PMIC, such as the battery status (charging, discharging, full, dead), current max limit, current current, battery capacity (in percentage), voltage max and min limits, current voltage and battery capacity (in Ah). Signed-off-by: Quentin Schulz Acked-by: Chen-Yu Tsai Acked-by: Maxime Ripard --- v4: - added monitored-battery optional property, - added example with battery, v3: - removed constant charge current property, now should use the WIP battery framework, v2: - changed DT node name from ac_power_supply to ac-power-supply, - removed io-channels and io-channel-names from DT (the IIO mapping is done in the IIO ADC driver now), - added x-powers,constant-charge-current property to set the maximal default constant current charge of the battery, .../bindings/power/supply/axp20x_battery.txt | 30 ++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 Documentation/devicetree/bindings/power/supply/axp20x_battery.txt diff --git a/Documentation/devicetree/bindings/power/supply/axp20x_battery.txt b/Documentation/devicetree/bindings/power/supply/axp20x_battery.txt new file mode 100644 index 0000000..89cb7a2 --- /dev/null +++ b/Documentation/devicetree/bindings/power/supply/axp20x_battery.txt @@ -0,0 +1,30 @@ +AXP20x and AXP22x battery power supply + +Required Properties: + - compatible, one of: + "x-powers,axp209-battery-power-supply" + "x-powers,axp221-battery-power-supply" + +Optional properties: + - monitored-battery, phandle to a fixed battery + +This node is a subnode of the axp20x/axp22x PMIC. + +The AXP20X and AXP22X can read the battery voltage, charge and discharge +currents of the battery by reading ADC channels from the AXP20X/AXP22X +ADC. + +Example: + +battery: battery { + compatible = "fixed-battery"; + voltage-min-design-microvolt = <3200000>; + constant-charge-microamp = <300000>; +}; + +&axp209 { + battery_power_supply: battery-power-supply { + compatible = "x-powers,axp209-battery-power-supply"; + monitored-battery = <&battery>; + } +};
