Add explicit pinctrl configuration for UART0 Signed-off-by: Sjoerd Simons --- V1 -> V2: Move pinctrl to the soc dtsi as it's the only available pinmux for the uart. And very rare for the pins to be used for anything else. --- arch/arm64/boot/dts/mediatek/mt7981b.dtsi | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/arch/arm64/boot/dts/mediatek/mt7981b.dtsi b/arch/arm64/boot/dts/mediatek/mt7981b.dtsi index 58c99f2a25218..4fa35bbf0a9cd 100644 --- a/arch/arm64/boot/dts/mediatek/mt7981b.dtsi +++ b/arch/arm64/boot/dts/mediatek/mt7981b.dtsi @@ -102,6 +102,8 @@ uart0: serial@11002000 { clocks = <&infracfg CLK_INFRA_UART0_SEL>, <&infracfg CLK_INFRA_UART0_CK>; clock-names = "baud", "bus"; + pinctrl-names = "default"; + pinctrl-0 = <&uart0_pins>; status = "disabled"; }; @@ -229,6 +231,13 @@ pio: pinctrl@11d00000 { gpio-controller; #gpio-cells = <2>; #interrupt-cells = <2>; + + uart0_pins: uart0-pins { + mux { + function = "uart"; + groups = "uart0"; + }; + }; }; efuse@11f20000 { -- 2.51.0
