The only change between these two compatibles is that PCS_HAS_PINCONF will be true. This then allows pinconf properties to be utilized. The purpose of this change is to allow the PocketBeagle to use: pinctrl-single,bias-pullup pinctrl-single,bias-pulldown This dts already defines these properites for gpio pins in the default pinctrl state but it has no effect unless PCS_HAS_PINCONF is set. The bias properties can then be modified on the corresponding gpio lines through the gpiod uapi. The mapping between the pins and gpio lines is defined by gpio-ranges under the gpio controller nodes in am33xx-l4.dtsi Signed-off-by: Drew Fustini --- arch/arm/boot/dts/am335x-pocketbeagle.dts | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/arm/boot/dts/am335x-pocketbeagle.dts b/arch/arm/boot/dts/am335x-pocketbeagle.dts index 209cdd17dc1e..5e415d8ffdd8 100644 --- a/arch/arm/boot/dts/am335x-pocketbeagle.dts +++ b/arch/arm/boot/dts/am335x-pocketbeagle.dts @@ -205,6 +205,7 @@ &gpio3 { &am33xx_pinmux { + compatible = "pinconf-single"; pinctrl-names = "default"; pinctrl-0 = < &P2_03_gpio &P1_34_gpio &P2_19_gpio &P2_24_gpio
