So pass the "sii,43wvf1g" compatible string, which describes the parallel LCD. Also pass the 'backlight' property as described in Documentation/devicetree/bindings/display/panel/simple-panel.txt Signed-off-by: Marco Franchi --- Changes since v1: -change subject -change message log -includes into a set of patches -rebase to linux-next -fix regulator name and properties arch/arm/boot/dts/imx6sx-sdb.dtsi | 48 +++++++++++++++++++-------------------- 1 file changed, 24 insertions(+), 24 deletions(-) diff --git a/arch/arm/boot/dts/imx6sx-sdb.dtsi b/arch/arm/boot/dts/imx6sx-sdb.dtsi index d57a41c..d35aa85 100644 --- a/arch/arm/boot/dts/imx6sx-sdb.dtsi +++ b/arch/arm/boot/dts/imx6sx-sdb.dtsi @@ -24,7 +24,7 @@ reg = <0x80000000 0x40000000>; }; - backlight { + backlight_display: backlight-display { compatible = "pwm-backlight"; pwms = <&pwm3 0 5000000>; brightness-levels = <0 4 8 16 32 64 128 255>; @@ -129,6 +129,13 @@ enable-active-high; }; + reg_lcd_5v: regulator-lcd-5v { + compatible = "regulator-fixed"; + regulator-name = "lcd-5v0"; + regulator-min-microvolt = <5000000>; + regulator-max-microvolt = <5000000>; + }; + sound { compatible = "fsl,imx6sx-sdb-wm8962", "fsl,imx-audio-wm8962"; model = "wm8962-audio"; @@ -144,6 +151,19 @@ mux-int-port = <2>; mux-ext-port = <6>; }; + + panel { + compatible = "sii,43wvf1g"; + backlight = <&backlight_display>; + dvdd-supply = <®_lcd_3v3>; + avdd-supply = <®_lcd_5v>; + + port { + panel_in: endpoint { + remote-endpoint = <&display_out>; + }; + }; + }; }; &audmux { @@ -221,31 +241,11 @@ &lcdif1 { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_lcd>; - lcd-supply = <®_lcd_3v3>; - display = <&display0>; status = "okay"; - display0: display0 { - bits-per-pixel = <16>; - bus-width = <24>; - - display-timings { - native-mode = <&timing0>; - timing0: timing0 { - clock-frequency = <33500000>; - hactive = <800>; - vactive = <480>; - hback-porch = <89>; - hfront-porch = <164>; - vback-porch = <23>; - vfront-porch = <10>; - hsync-len = <10>; - vsync-len = <10>; - hsync-active = <0>; - vsync-active = <0>; - de-active = <1>; - pixelclk-active = <0>; - }; + port { + display_out: endpoint { + remote-endpoint = <&panel_in>; }; }; }; -- 2.7.4
