dt-bindings: display: panel: convert truly,nt35597.txt to dt-schema
Convert the Truly NT35597 2K display panel bindings to dt-schema.
The vdispp-supply & vdispn-supply are not marked as required since
in practice they are not defined in sdm845-mtp.dts which is the
only used of these bindings.

Truly model NT35597 DSI display driver
2
-
3
-
The Truly NT35597 is a generic display driver, currently only configured
4
-
for use in the 2K display on the Qualcomm SDM845 MTP board.
5
-
6
-
Required properties:
7
-
- compatible: should be "truly,nt35597-2K-display"
8
-
- vdda-supply: phandle of the regulator that provides the supply voltage
9
-
Power IC supply
10
-
- vdispp-supply: phandle of the regulator that provides the supply voltage
11
-
for positive LCD bias
12
-
- vdispn-supply: phandle of the regulator that provides the supply voltage
13
-
for negative LCD bias
14
-
- reset-gpios: phandle of gpio for reset line
15
-
This should be 8mA, gpio can be configured using mux, pinctrl, pinctrl-names
16
-
(active low)
17
-
- mode-gpios: phandle of the gpio for choosing the mode of the display
18
-
for single DSI or Dual DSI
19
-
This should be low for dual DSI and high for single DSI mode
20
-
- ports: This device has two video ports driven by two DSIs. Their connections
21
-
are modeled using the OF graph bindings specified in
22
-
Documentation/devicetree/bindings/graph.txt.
23
-
- port@0: DSI input port driven by master DSI
24
-
- port@1: DSI input port driven by secondary DSI
