Add the device tree bindings for Truly NT35597 panel.
This panel supports both single DSI and dual DSI.
However, this patch series supports only dual DSI.
Changes in v5:
- None

+Truly model NT35597 1440x2560 DSI Panel
+
+Required properties:
+- compatible: should be "truly,nt35597"
+- 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
+- display-timings: Node for the Panel timings
+- 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@0: DSI input port driven by master DSI
+ - port@1: DSI input port driven by secondary DSI
+
+Example:

+ pinctrl-names = "default", "suspend";
+ pinctrl-0 = <&dpu_dsi_active>;
+ pinctrl-1 = <&dpu_dsi_suspend>;
+
+ reset-gpios = <&tlmm 6 0>;
+ mode-gpios = <&tlmm 52 0>;
