[PATCH v6 2/2] dt-bindings: Add Truly NT35597 panel driver bindings

[Abhinav Kumar]

From: "abhinavk at codeaurora.org" <abhinavk at codeaurora.org>

Add the device tree bindings for Truly NT35597 panel driver.
This panel driver supports both single DSI and dual DSI.

However, this patch series supports only dual DSI.

Changes in v6:
  - Change the compatible string to indicate the
    reference board and the panel
  - Remove the display timing node

+Truly model NT35597 1440x2560 DSI Panel
+
+Required properties:
+- compatible: should be "qcom,sdm845-mtp-2K-display"
+- vdda-supply: phandle of the regulator that provides the supply voltage
+  Power IC supply
+- vdispp-supply: phandle of the regulator that provides the supply voltage
+  for positive LCD bias
+- vdispn-supply: phandle of the regulator that provides the supply voltage
+  for negative LCD bias
+- reset-gpios: phandle of gpio for reset line
+  This should be 8mA, gpio can be configured using mux, pinctrl, pinctrl-names
+- mode-gpios: phandle of the gpio for choosing the mode of the display
+  for single DSI or Dual DSI
+  This should be low for dual DSI and high for single DSI mode
+- ports: This device has two video ports driven by two DSIs. Their connections
+  are modelled using the OF graph bindings specified in
+  Documentation/devicetree/bindings/graph.txt.
+  - port at 0: DSI input port driven by master DSI
+  - port at 1: DSI input port driven by secondary DSI
+
+Example:
+
+	dsi at ae94000 {
+		panel at 0 {
+			compatible = "qcom,sdm845-mtp-2K-display";
+			reg = <0>;
+			vdda-supply = <&pm8998_l14>;
+			vdispp-supply = <&lab_regulator>;
+			vdispn-supply = <&ibb_regulator>;
+			pinctrl-names = "default", "suspend";
+			pinctrl-0 = <&dpu_dsi_active>;
+			pinctrl-1 = <&dpu_dsi_suspend>;
+
+			reset-gpios = <&tlmm 6 0>;
+			mode-gpios = <&tlmm 52 0>;
+			ports {
+				#address-cells = <1>;
+				#size-cells = <0>;
+				port at 0 {
+					reg = <0>;
+					panel0_in: endpoint {
+						remote-endpoint = <&dsi0_out>;
+					};
+				};
+
+				port at 1 {
+					reg = <1>;
+					panel1_in: endpoint {
+						remote-endpoint = <&dsi1_out>;
+					};
+				};
+			};
+		};
+	};
