Signed-off-by: Baolin Wang Reviewed-by: Linus Walleij Reviewed-by: Rob Herring --- Changes from v3: Add reviewed tag from Rob. Changes from v2: - Add reviewed tag from Linus. Changes from v1: - Renamed GPIO property. - Use standand battery properties instead of 'sprd,inner-resist' and 'sprd,ocv-cap-table'. - Remove battery node's description. --- .../devicetree/bindings/power/supply/sc27xx-fg.txt | 52 ++++++++++++++++++++ 1 file changed, 52 insertions(+) create mode 100644 Documentation/devicetree/bindings/power/supply/sc27xx-fg.txt diff --git a/Documentation/devicetree/bindings/power/supply/sc27xx-fg.txt b/Documentation/devicetree/bindings/power/supply/sc27xx-fg.txt new file mode 100644 index 0000000..98a2400 --- /dev/null +++ b/Documentation/devicetree/bindings/power/supply/sc27xx-fg.txt @@ -0,0 +1,52 @@ +Spreadtrum SC27XX PMICs Fuel Gauge Unit Power Supply Bindings + +Required properties: +- compatible: Should be one of the following: + "sprd,sc2720-fgu", + "sprd,sc2721-fgu", + "sprd,sc2723-fgu", + "sprd,sc2730-fgu", + "sprd,sc2731-fgu". +- reg: The address offset of fuel gauge unit. +- battery-detect-gpios: GPIO for battery detection. +- io-channels: Specify the IIO ADC channel to get temperature. +- io-channel-names: Should be "bat-temp". +- monitored-battery: Phandle of battery characteristics devicetree node. + See Documentation/devicetree/bindings/power/supply/battery.txt + +Example: + + bat: battery { + compatible = "simple-battery"; + charge-full-design-microamp-hours = <1900000>; + constant-charge-voltage-max-microvolt = <4350000>; + ocv-capacity-celsius = <20>; + ocv-capacity-table-0 = <4185000 100>, <4113000 95>, <4066000 90>, + <4022000 85>, <3983000 80>, <3949000 75>, + <3917000 70>, <3889000 65>, <3864000 60>, + <3835000 55>, <3805000 50>, <3787000 45>, + <3777000 40>, <3773000 35>, <3770000 30>, + <3765000 25>, <3752000 20>, <3724000 15>, + <3680000 10>, <3605000 5>, <3400000 0>; + ...... + }; + + sc2731_pmic: pmic@0 { + compatible = "sprd,sc2731"; + reg = <0>; + spi-max-frequency = <26000000>; + interrupts = ; + interrupt-controller; + #interrupt-cells = <2>; + #address-cells = <1>; + #size-cells = <0>; + + fgu@a00 { + compatible = "sprd,sc2731-fgu"; + reg = <0xa00>; + battery-detect-gpios = <&pmic_eic 9 GPIO_ACTIVE_HIGH>; + io-channels = <&pmic_adc 5>; + io-channel-names = "bat-temp"; + monitored-battery = <&bat>; + }; + }; -- 1.7.9.5
