This patch add support for Bananapi S070WV20-CT16 DSI panel to BPI-M2U board. DSI panel connected via board DSI port with, - DCDC1 as VCC-DSI supply - PH18 gpio for lcd enable pin - PD17 gpio for lcd reset pin - PD16 gpio for backlight enable pin Signed-off-by: Jagan Teki <jagan@xxxxxxxxxxxxxxxxxxxx> --- .../boot/dts/sun8i-r40-bananapi-m2-ultra.dts | 36 +++++++++++++++++++ 1 file changed, 36 insertions(+) diff --git a/arch/arm/boot/dts/sun8i-r40-bananapi-m2-ultra.dts b/arch/arm/boot/dts/sun8i-r40-bananapi-m2-ultra.dts index c488aaacbd68..5f39317b783e 100644 --- a/arch/arm/boot/dts/sun8i-r40-bananapi-m2-ultra.dts +++ b/arch/arm/boot/dts/sun8i-r40-bananapi-m2-ultra.dts @@ -45,6 +45,7 @@ #include "sun8i-r40.dtsi" #include <dt-bindings/gpio/gpio.h> +#include <dt-bindings/pwm/pwm.h> / { model = "Banana Pi BPI-M2-Ultra"; @@ -55,6 +56,14 @@ serial0 = &uart0; }; + backlight: backlight { + compatible = "pwm-backlight"; + pwms = <&pwm 0 50000 PWM_POLARITY_INVERTED>; + brightness-levels = <1 2 4 8 16 32 64 128 255>; + default-brightness-level = <8>; + enable-gpios = <&pio 7 16 GPIO_ACTIVE_HIGH>; /* LCD-BL-EN: PH16 */ + }; + chosen { stdout-path = "serial0:115200n8"; }; @@ -117,6 +126,23 @@ status = "okay"; }; +&dphy { + status = "okay"; +}; + +&dsi { + vcc-dsi-supply = <®_dcdc1>; /* VCC-DSI */ + status = "okay"; + + panel@0 { + compatible = "bananapi,s070wv20-ct16-icn6211"; + reg = <0>; + enable-gpio = <&pio 7 18 GPIO_ACTIVE_HIGH>; /* LCD-PWR-EN: PH18 */ + reset-gpios = <&pio 7 17 GPIO_ACTIVE_HIGH>; /* LCD-RST: PH17 */ + backlight = <&backlight>; + }; +}; + &ehci1 { status = "okay"; }; @@ -203,6 +229,12 @@ pinctrl-0 = <&clk_out_a_pin>; }; +&pwm { + pinctrl-names = "default"; + pinctrl-0 = <&pwm_pins>; + status = "okay"; +}; + ®_aldo2 { regulator-always-on; regulator-min-microvolt = <2500000>; @@ -290,6 +322,10 @@ regulator-name = "vdd1v2-sata"; }; +&tcon_lcd0 { + status = "okay"; +}; + &tcon_tv0 { status = "okay"; }; -- 2.18.0.321.gffc6fa0e3 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
