dt-bindings: Add Truly NT35597 panel driver bindings 



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 v10:
  - Remove active high in the documentation for mode gpio
  - Fix commmit text detail about the board and also
    fix a typo

Truly model NT35597 DSI display driver



The Truly NT35597 is a generic display driver, currently only configured

for use in the 2K display on the Qualcomm SDM845 MTP board.



Required properties:

- compatible: should be "truly,nt35597-2K-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

  (active low)

- 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 modeled using the OF graph bindings specified in

  Documentation/devicetree/bindings/graph.txt.

  - port@0: DSI input port driven by master DSI

  - port@1: DSI input port driven by secondary DSI



Example:



	dsi@ae94000 {

		panel@0 {

			compatible = "truly,nt35597-2K-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 GPIO_ACTIVE_LOW>;

			mode-gpios = <&tlmm 52 GPIO_ACTIVE_HIGH>;

			ports {

				#address-cells = <1>;

				#size-cells = <0>;

				port@0 {

					reg = <0>;

					panel0_in: endpoint {

						remote-endpoint = <&dsi0_out>;

					};

				};



				port@1 {

					reg = <1>;

					panel1_in: endpoint {

						remote-endpoint = <&dsi1_out>;

					};

				};

			};

		};

	};
