Subject: [PATCH 2/4] dt-bindings: Add ANX6345 DP/eDP transmitter binding

From: Icenowy Zheng <[email protected]>

The ANX6345 is an ultra-low power DisplayPort/eDP transmitter designed
for portable devices.

Add a binding document for it.

All I did is change the reset polarity, which is evidently active low;
according to the (terse) datasheet. It matches the polarity in the last
patch.

+Analogix ANX6345 eDP Transmitter
+--------------------------------
+
+The ANX6345 is an ultra-low power Full-HD eDP transmitter designed for
+portable devices.
+
+Required properties:
+
+ - compatible : "analogix,anx6345"
+ - reg : I2C address of the device
+ - reset-gpios : Which GPIO to use for reset
+
+Optional properties:
+
+ - dvdd12-supply : Regulator for 1.2V digital core power.
+ - dvdd25-supply : Regulator for 2.5V digital core power.
+ - Video ports for RGB input and eDP output using the DT bindings
+ defined in [1]
+
+[1]: Documentation/devicetree/bindings/media/video-interfaces.txt
+
+Example:
+
+anx6345: anx6345@38 {
+ compatible = "analogix,anx6345";
+ reg = <0x38>;
+ reset-gpios = <&pio 3 24 GPIO_ACTIVE_LOW>; /* PD24 */
+ dvdd25-supply = <&reg_dldo2>;
+ dvdd12-supply = <&reg_fldo1>;
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ anx6345_in: port@0 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0>;
+ anx6345_in_tcon0: endpoint@0 {
+ reg = <0>;
+ remote-endpoint = <&tcon0_out_anx6345>;
+ };
+ };
+
+ anx6345_out: port@1 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <1>;
+
+ anx6345_out_panel: endpoint@0 {
+ reg = <0>;
+ remote-endpoint = <&panel_in_edp>;
