It uses the TPU0 as backlight, one GPIO pull-up configuration for power enable, R[2:7], G[2:7], B[2:7], VSYNC, HSYNC, DU0_DISP and, DU0_CLK as inputs. There is no encoder between the DU and the panel, therefore the default connector driver is used. The two variants of the iW-G22D should be mutually exclusive, therefore this patch also disables the RGB LCD display when the HDMI extension board is used. Changes for v2: - fix the backlight of the panel - remove "simple-panel" compatible as it is not needed - use only one port for the endpoint connection of the panel Signed-off-by: Marian-Cristian Rotariu Reviewed-by: Geert Uytterhoeven --- .../arm/boot/dts/r8a7745-iwg22d-sodimm-dbhd-ca.dts | 6 +++ arch/arm/boot/dts/r8a7745-iwg22d-sodimm.dts | 60 ++++++++++++++++++++++ 2 files changed, 66 insertions(+) diff --git a/arch/arm/boot/dts/r8a7745-iwg22d-sodimm-dbhd-ca.dts b/arch/arm/boot/dts/r8a7745-iwg22d-sodimm-dbhd-ca.dts index 2aeebfc..92aa26b 100644 --- a/arch/arm/boot/dts/r8a7745-iwg22d-sodimm-dbhd-ca.dts +++ b/arch/arm/boot/dts/r8a7745-iwg22d-sodimm-dbhd-ca.dts @@ -108,6 +108,12 @@ }; }; +&lcd_panel { + status = "disabled"; + + /delete-node/ port; +}; + &pfc { can1_pins: can1 { groups = "can1_data_b"; diff --git a/arch/arm/boot/dts/r8a7745-iwg22d-sodimm.dts b/arch/arm/boot/dts/r8a7745-iwg22d-sodimm.dts index ce6603b..872f8a6 100644 --- a/arch/arm/boot/dts/r8a7745-iwg22d-sodimm.dts +++ b/arch/arm/boot/dts/r8a7745-iwg22d-sodimm.dts @@ -30,6 +30,7 @@ /dts-v1/; #include "r8a7745-iwg22m.dtsi" +#include / { model = "iWave Systems RainboW-G22D-SODIMM board based on RZ/G1E"; @@ -79,6 +80,49 @@ states = <3300000 1 1800000 0>; }; + + vccq_panel: regulator-vccq-panel { + compatible = "regulator-fixed"; + regulator-name = "Panel VccQ"; + regulator-min-microvolt = <3300000>; + regulator-max-microvolt = <3300000>; + gpio = <&gpio1 13 GPIO_ACTIVE_LOW>; + enable-active-high; + }; + + backlight_lcd: backlight { + compatible = "pwm-backlight"; + pwms = <&tpu 3 5000000 PWM_POLARITY_INVERTED>; + brightness-levels = <0 4 8 16 32 64 128 255>; + default-brightness-level = <7>; + }; + + lcd_panel: lcd { + compatible = "edt,etm043080dh6gp"; + power-supply = <&vccq_panel>; + backlight = <&backlight_lcd>; + + port { + lcd_in: endpoint { + remote-endpoint = <&du_out_rgb0>; + }; + }; + }; +}; + +&du { + pinctrl-0 = <&du0_pins>; + pinctrl-names = "default"; + + status = "okay"; + + ports { + port@0 { + endpoint { + remote-endpoint = <&lcd_in>; + }; + }; + }; }; &avb { @@ -150,11 +194,21 @@ function = "avb"; }; + backlight_pins: backlight { + renesas,groups = "tpu_to3_c"; + renesas,function = "tpu"; + }; + can0_pins: can0 { groups = "can0_data"; function = "can0"; }; + du0_pins: du0 { + renesas,groups = "du0_rgb666", "du0_sync", "du0_disp", "du0_clk0_out"; + renesas,function = "du0"; + }; + hscif1_pins: hscif1 { groups = "hscif1_data", "hscif1_ctrl"; function = "hscif1"; @@ -230,6 +284,12 @@ shared-pin; }; +&tpu { + pinctrl-0 = <&backlight_pins>; + pinctrl-names = "default"; + status = "okay"; +}; + &usbphy { status = "okay"; };
