From the datasheet, the active level is low. Although it's already configured to logic low at driver probe function, but the current binding example declared it as 'GPIO_ACTIVE_LOW', this causes this pin be output high and disable battery charging. Fixes: e1b4620fb503 ("dt-bindings: power: supply: Add Richtek RT9467 battery charger") Signed-off-by: ChiYuan Huang --- Hi, This patch is to fix the active level for charger enable gpio polarity. Currently, the wrong active level makes the user confused and unexpectedly disable battery charging by default. --- Documentation/devicetree/bindings/power/supply/richtek,rt9467.yaml | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/Documentation/devicetree/bindings/power/supply/richtek,rt9467.yaml b/Documentation/devicetree/bindings/power/supply/richtek,rt9467.yaml index 3723717..cdc7678 100644 --- a/Documentation/devicetree/bindings/power/supply/richtek,rt9467.yaml +++ b/Documentation/devicetree/bindings/power/supply/richtek,rt9467.yaml @@ -69,7 +69,7 @@ examples: reg = <0x5b>; wakeup-source; interrupts-extended = <&gpio_intc 32 IRQ_TYPE_LEVEL_LOW>; - charge-enable-gpios = <&gpio26 1 GPIO_ACTIVE_LOW>; + charge-enable-gpios = <&gpio26 1 GPIO_ACTIVE_HIGH>; rt9467_otg_vbus: usb-otg-vbus-regulator { regulator-name = "rt9467-usb-otg-vbus";
