1 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
