The pinmux is already correct, so just correct the GPIO number. Fixes: 4a13b3bec3b4 (arm64: dts: imx: add Zii Ultra board support) Signed-off-by: Lucas Stach --- Urgh, second fix for this regulator, it was really wrong in the beginning. This time I actually measured the voltage on the board and saw it changing as expected, so hopefully we are good now. --- arch/arm64/boot/dts/freescale/imx8mq-zii-ultra.dtsi | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm64/boot/dts/freescale/imx8mq-zii-ultra.dtsi b/arch/arm64/boot/dts/freescale/imx8mq-zii-ultra.dtsi index 087b5b6ebe89..32ce14936b01 100644 --- a/arch/arm64/boot/dts/freescale/imx8mq-zii-ultra.dtsi +++ b/arch/arm64/boot/dts/freescale/imx8mq-zii-ultra.dtsi @@ -88,7 +88,7 @@ regulator-name = "0V9_ARM"; regulator-min-microvolt = <900000>; regulator-max-microvolt = <1000000>; - gpios = <&gpio3 19 GPIO_ACTIVE_HIGH>; + gpios = <&gpio3 16 GPIO_ACTIVE_HIGH>; states = <1000000 0x1 900000 0x0>; regulator-always-on;
