I've just tested this series and the internal screen works with this too. Screenblank still seems to freeze the kernel though. Eg. # setterm --powersave on # setterm --blank 1 # < wait 1 minute > But getting output on the screen is progress ;) As for the spi change suspend now works too, which it didn't before, but the screen just didn't come up properly after the suspend. I could still ssh into it after suspend though. /Emil >>> >>> arch/arm64/boot/dts/rockchip/rk3399-gru-kevin.dts | 29 +++++++++++++++++++++++ >>> arch/arm64/boot/dts/rockchip/rk3399-gru.dtsi | 16 +++++++++++++ >>> 2 files changed, 45 insertions(+) >>> >>> diff --git a/arch/arm64/boot/dts/rockchip/rk3399-gru-kevin.dts b/arch/arm64/boot/dts/rockchip/rk3399-gru-kevin.dts >>> index a3d3cea7dc4f..bc67b19f0af5 100644 >>> --- a/arch/arm64/boot/dts/rockchip/rk3399-gru-kevin.dts >>> +++ b/arch/arm64/boot/dts/rockchip/rk3399-gru-kevin.dts >>> @@ -93,6 +93,18 @@ >>> pwm-delay-us = <10000>; >>> }; >>> >>> + edp_panel: edp-panel { >>> + compatible = "sharp,lq123p1jx31", "simple-panel"; >>> + backlight = <&backlight>; >>> + power-supply = <&pp3300_disp>; >>> + >>> + ports { >>> + panel_in_edp: endpoint { >>> + remote-endpoint = <&edp_out_panel>; >>> + }; >>> + }; >>> + }; >>> + >>> thermistor_ppvar_bigcpu: thermistor-ppvar-bigcpu { >>> compatible = "murata,ncp15wb473"; >>> pullup-uv = <1800000>; >>> @@ -264,6 +276,23 @@ ap_i2c_dig: &i2c2 { >>> }; >>> }; >>> >>> +&edp { >>> + status = "okay"; >>> + >>> + ports { >>> + edp_out: port@1 { >>> + reg = <1>; >>> + #address-cells = <1>; >>> + #size-cells = <0>; >>> + >>> + edp_out_panel: endpoint@0 { >>> + reg = <0>; >>> + remote-endpoint = <&panel_in_edp>; >>> + }; >>> + }; >>> + }; >>> +}; >>> + >>> &ppvar_bigcpu_pwm { >>> regulator-min-microvolt = <798674>; >>> regulator-max-microvolt = <1302172>; >>> diff --git a/arch/arm64/boot/dts/rockchip/rk3399-gru.dtsi b/arch/arm64/boot/dts/rockchip/rk3399-gru.dtsi >>> index 5772c52fbfd3..470105d651c2 100644 >>> --- a/arch/arm64/boot/dts/rockchip/rk3399-gru.dtsi >>> +++ b/arch/arm64/boot/dts/rockchip/rk3399-gru.dtsi >>> @@ -927,6 +927,22 @@ ap_i2c_audio: &i2c8 { >>> dr_mode = "host"; >>> }; >>> >>> +&vopb { >>> + status = "okay"; >>> +}; >>> + >>> +&vopb_mmu { >>> + status = "okay"; >>> +}; >>> + >>> +&vopl { >>> + status = "okay"; >>> +}; >>> + >>> +&vopl_mmu { >>> + status = "okay"; >>> +}; >>> + >>> #include <arm/cros-ec-keyboard.dtsi> >>> #include <arm/cros-ec-sbs.dtsi> >>> >>> >> >> >> >> _______________________________________________ >> Linux-rockchip mailing list >> Linux-rockchip@xxxxxxxxxxxxxxxxxxx >> http://lists.infradead.org/mailman/listinfo/linux-rockchip -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
