Truly model NT35597 DSI display driver
|
||
|
|
|
||
|
|
The Truly NT35597 is a generic display driver, currently only configured
|
||
|
|
for use in the 2K display on the Qualcomm SDM845 MTP board.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: should be "truly,nt35597-2K-display"
|
||
|
|
- 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
|
||
|
|
(active low)
|
||
|
|
- 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
|
||
|
|
- ports: This device has two video ports driven by two DSIs. Their connections
|
||
|
|
are modeled 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
|
||
|
|
|
||
|
|
