   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
