From 33d9fc06cae240f1ba769caa40d5b023c0c38cee Mon Sep 17 00:00:00 2001 From: Jorik Jonker Date: Mon, 12 Sep 2016 20:12:45 +0200 Subject: [PATCH] dts: sun8i-h3: associate exposed UARTs on Orange Pi Boards These H3 boards all expose UART1-3 on their expansion header. Since other functions can be muxed to these pins, they are explicitly disabled. To enable them, one could use DT overlays or U-boot commands: => fdt set /soc/serial@01c28c00 status okay Signed-off-by: Jorik Jonker Signed-off-by: Maxime Ripard --- arch/arm/boot/dts/sun8i-h3-orangepi-2.dts | 18 ++++++++++++++++++ arch/arm/boot/dts/sun8i-h3-orangepi-one.dts | 18 ++++++++++++++++++ arch/arm/boot/dts/sun8i-h3-orangepi-pc.dts | 18 ++++++++++++++++++ 3 files changed, 54 insertions(+) diff --git a/arch/arm/boot/dts/sun8i-h3-orangepi-2.dts b/arch/arm/boot/dts/sun8i-h3-orangepi-2.dts index f89fe00ddec5..e5bcaba3e87f 100644 --- a/arch/arm/boot/dts/sun8i-h3-orangepi-2.dts +++ b/arch/arm/boot/dts/sun8i-h3-orangepi-2.dts @@ -186,6 +186,24 @@ status = "okay"; }; +&uart1 { + pinctrl-names = "default"; + pinctrl-0 = <&uart1_pins>; + status = "disabled"; +}; + +&uart2 { + pinctrl-names = "default"; + pinctrl-0 = <&uart2_pins>; + status = "disabled"; +}; + +&uart3 { + pinctrl-names = "default"; + pinctrl-0 = <&uart3_pins>; + status = "disabled"; +}; + &usb1_vbus_pin_a { allwinner,pins = "PG13"; }; diff --git a/arch/arm/boot/dts/sun8i-h3-orangepi-one.dts b/arch/arm/boot/dts/sun8i-h3-orangepi-one.dts index 0adf932fd923..5c9b5bfa5c21 100644 --- a/arch/arm/boot/dts/sun8i-h3-orangepi-one.dts +++ b/arch/arm/boot/dts/sun8i-h3-orangepi-one.dts @@ -139,6 +139,24 @@ status = "okay"; }; +&uart1 { + pinctrl-names = "default"; + pinctrl-0 = <&uart1_pins>; + status = "disabled"; +}; + +&uart2 { + pinctrl-names = "default"; + pinctrl-0 = <&uart2_pins>; + status = "disabled"; +}; + +&uart3 { + pinctrl-names = "default"; + pinctrl-0 = <&uart3_pins>; + status = "disabled"; +}; + &usbphy { /* USB VBUS is always on */ status = "okay"; diff --git a/arch/arm/boot/dts/sun8i-h3-orangepi-pc.dts b/arch/arm/boot/dts/sun8i-h3-orangepi-pc.dts index daf50b9a6657..3ec971285aa3 100644 --- a/arch/arm/boot/dts/sun8i-h3-orangepi-pc.dts +++ b/arch/arm/boot/dts/sun8i-h3-orangepi-pc.dts @@ -161,6 +161,24 @@ status = "okay"; }; +&uart1 { + pinctrl-names = "default"; + pinctrl-0 = <&uart1_pins>; + status = "disabled"; +}; + +&uart2 { + pinctrl-names = "default"; + pinctrl-0 = <&uart2_pins>; + status = "disabled"; +}; + +&uart3 { + pinctrl-names = "default"; + pinctrl-0 = <&uart3_pins>; + status = "disabled"; +}; + &usbphy { /* USB VBUS is always on */ status = "okay"; -- 2.20.1
