Also the message isn't really concise. The main entries for the DSI controller and the PHY are in sc7180.dtsi. I would suggest to drop any mentions of DSI controller and PHYs, and just say something like 'Add nodes for IDP display'. In the body you could mention that the display is the Visionox RM69299. > Adding dsi controller and phy entries for idp dt. > > Signed-off-by: Harigovindan P <harigovi@xxxxxxxxxxxxxx> > --- > > Changes in v1: > - Added dsi controller and dsi phy entries for idp dts Changes in v1 is pointless, it's the first patch > Changes in v2: > - Adding dependency patchwork series > - Removing suspend configuration > - Adding blank before curly brace > > This patch depends on following patchwork series: > > https://patchwork.kernel.org/patch/11364687/ > https://patchwork.kernel.org/patch/11366303/ > > arch/arm64/boot/dts/qcom/sc7180-idp.dts | 55 +++++++++++++++++++++++++ > 1 file changed, 55 insertions(+) > > diff --git a/arch/arm64/boot/dts/qcom/sc7180-idp.dts b/arch/arm64/boot/dts/qcom/sc7180-idp.dts > index 388f50ad4fde..6ccf8c3603ab 100644 > --- a/arch/arm64/boot/dts/qcom/sc7180-idp.dts > +++ b/arch/arm64/boot/dts/qcom/sc7180-idp.dts > @@ -7,6 +7,7 @@ > > /dts-v1/; > > +#include <dt-bindings/gpio/gpio.h> > #include <dt-bindings/regulator/qcom,rpmh-regulator.h> > #include "sc7180.dtsi" > #include "pm6150.dtsi" > @@ -232,6 +233,49 @@ vreg_bob: bob { > }; > }; > > +&dsi0 { > + status = "okay"; > + > + vdda-supply = <&vreg_l3c_1p2>; > + > + panel@0 { > + compatible = "visionox,rm69299-1080p-display"; > + reg = <0>; > + > + vdda-supply = <&vreg_l8c_1p8>; > + vdd3p3-supply = <&vreg_l18a_2p8>; > + > + pinctrl-names = "default"; > + pinctrl-0 = <&disp_pins>; > + > + reset-gpios = <&pm6150l_gpio 3 GPIO_ACTIVE_HIGH>; > + > + ports { > + #address-cells = <1>; > + #size-cells = <0>; > + port@0 { > + reg = <0>; > + panel0_in: endpoint { > + remote-endpoint = <&dsi0_out>; > + }; > + }; > + }; > + }; > + > + ports { > + port@1 { > + endpoint { > + remote-endpoint = <&panel0_in>; > + data-lanes = <0 1 2 3>; > + }; > + }; > + }; > +}; > + > +&dsi_phy { > + status = "okay"; > +}; > + > &qspi { > status = "okay"; > pinctrl-names = "default"; > @@ -289,6 +333,17 @@ &usb_1_qmpphy { > > /* PINCTRL - additions to nodes defined in sc7180.dtsi */ > > +&pm6150l_gpio { > + disp_pins: disp-pins { > + pins = "gpio3"; > + function = "func1"; > + qcom,drive-strength = <2>; > + power-source = <0>; > + bias-disable; > + output-low; > + }; > +}; > + > &qspi_clk { > pinconf { > pins = "gpio63"; To get the display actually to work you also need this: diff --git a/arch/arm64/boot/dts/qcom/sc7180-idp.dts b/arch/arm64/boot/dts/qcom/sc7180-idp.dts index 88919da1510b03..fdbcb56dfa81f9 100644 --- a/arch/arm64/boot/dts/qcom/sc7180-idp.dts +++ b/arch/arm64/boot/dts/qcom/sc7180-idp.dts @@ -276,6 +276,14 @@ status = "okay"; }; +&mdp { + status = "okay"; +}; + +&mdss { + status = "okay"; +}; + &qspi { status = "okay"; pinctrl-names = "default"; Maybe just add this to this patch?
