Enable Display Subsystem with Novatek NT36672E Panel on qcm6490 idp platform. Signed-off-by: Ritesh Kumar <quic_riteshk@xxxxxxxxxxx> --- v2: Fixed review comments from Dmitry and Konrad - moved pinctrl-names after pinctrl-0 property. - removed gpu disablement change after validating gpu. Rebased the patch - rebased the patch to resolve conflicts. v3: Fixed review comments from Dmitry - renamed panel supply to regulator-lcd-disp-bias. - moved backlight as per sort order. --- arch/arm64/boot/dts/qcom/qcm6490-idp.dts | 92 ++++++++++++++++++++++++ 1 file changed, 92 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/qcm6490-idp.dts b/arch/arm64/boot/dts/qcom/qcm6490-idp.dts index 502a5a383bde..6d6506726827 100644 --- a/arch/arm64/boot/dts/qcom/qcm6490-idp.dts +++ b/arch/arm64/boot/dts/qcom/qcm6490-idp.dts @@ -10,6 +10,7 @@ #define PM7250B_SID1 9 #include <dt-bindings/leds/common.h> +#include <dt-bindings/pinctrl/qcom,pmic-gpio.h> #include <dt-bindings/regulator/qcom,rpmh-regulator.h> #include "sc7280.dtsi" #include "pm7250b.dtsi" @@ -35,10 +36,29 @@ serial0 = &uart5; }; + pm8350c_pwm_backlight: backlight { + compatible = "pwm-backlight"; + pwms = <&pm8350c_pwm 3 65535>; + enable-gpios = <&pm8350c_gpios 7 GPIO_ACTIVE_HIGH>; + pinctrl-0 = <&pmic_lcd_bl_en>; + pinctrl-names = "default"; + }; + chosen { stdout-path = "serial0:115200n8"; }; + lcd_disp_bias: regulator-lcd-disp-bias { + compatible = "regulator-fixed"; + regulator-name = "lcd_disp_bias"; + regulator-min-microvolt = <5500000>; + regulator-max-microvolt = <5500000>; + gpio = <&pm7250b_gpios 2 GPIO_ACTIVE_HIGH>; + enable-active-high; + pinctrl-0 = <&lcd_disp_bias_en>; + pinctrl-names = "default"; + }; + reserved-memory { xbl_mem: xbl@80700000 { reg = <0x0 0x80700000 0x0 0x100000>; @@ -421,7 +441,79 @@ }; }; +&mdss { + status = "okay"; +}; + +&mdss_dsi { + vdda-supply = <&vreg_l6b_1p2>; + status = "okay"; + + panel@0 { + compatible = "novatek,nt36672e"; + reg = <0>; + + reset-gpios = <&tlmm 44 GPIO_ACTIVE_HIGH>; + + vddi-supply = <&vreg_l8c_1p62>; + avdd-supply = <&lcd_disp_bias>; + avee-supply = <&lcd_disp_bias>; + + backlight = <&pm8350c_pwm_backlight>; + + port { + panel0_in: endpoint { + remote-endpoint = <&mdss_dsi0_out>; + }; + }; + }; +}; + +&mdss_dsi0_out { + remote-endpoint = <&panel0_in>; + data-lanes = <0 1 2 3>; +}; + +&mdss_dsi_phy { + vdds-supply = <&vreg_l10c_0p88>; + status = "okay"; +}; + +&pm7250b_gpios { + lcd_disp_bias_en: lcd-disp-bias-en-state { + pins = "gpio2"; + function = "func1"; + bias-disable; + qcom,drive-strength = <PMIC_GPIO_STRENGTH_LOW>; + input-disable; + output-enable; + power-source = <0>; + }; +}; + +&pm8350c_gpios { + pmic_lcd_bl_en: pmic-lcd-bl-en-state { + pins = "gpio7"; + function = "normal"; + bias-disable; + qcom,drive-strength = <PMIC_GPIO_STRENGTH_LOW>; + output-low; + power-source = <0>; + }; + + pmic_lcd_bl_pwm: pmic-lcd-bl-pwm-state { + pins = "gpio8"; + function = "func1"; + bias-disable; + qcom,drive-strength = <PMIC_GPIO_STRENGTH_LOW>; + output-low; + power-source = <0>; + }; +}; + &pm8350c_pwm { + pinctrl-0 = <&pmic_lcd_bl_pwm>; + pinctrl-names = "default"; status = "okay"; multi-led { -- 2.17.1
