From: Archit Taneja <architt@xxxxxxxxxxxxxx>
Add support for Truly NT35597 panel used
in MSM reference platforms.
Changes in v2:
- Renamed panel to truly,nt35597
- Added SPDX license
- Used endpoints instead of custom node
- Renamed and cleaned up power supplies

+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
+
+Example:
+
+ dsi@ae94000 {
+ panel@0 {
+ compatible = "truly,nt35597";
+ reg = <0>;
+ vdda-supply = <&pm8998_l14>;
+ vdispp-supply = <&lab_regulator>;
+ vdispn-supply = <&ibb_regulator>;
+ pinctrl-names = "default", "suspend";
+ pinctrl-0 = <&sde_dsi_active>;
+ pinctrl-1 = <&sde_dsi_suspend>;
+
+ reset-gpios = <&tlmm 6 0>;
+ mode-gpios = <&tlmm 52 0>;
+ display-timings {
+ timing0: timing-0 {
+ clock-frequency = <268316138>;
+ hactive = <1440>;
+ vactive = <2560>;
+ hfront-porch = <200>;
