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
Example:
dsi@ae94000 {
panel@0 {
compatible = "truly,nt35597-2K-display";
reg = <0>;
vdda-supply = <&pm8998_l14>;
vdispp-supply = <&lab_regulator>;
vdispn-supply = <&ibb_regulator>;
pinctrl-names = "default", "suspend";
pinctrl-0 = <&dpu_dsi_active>;
pinctrl-1 = <&dpu_dsi_suspend>;
reset-gpios = <&tlmm 6 GPIO_ACTIVE_LOW>;
mode-gpios = <&tlmm 52 GPIO_ACTIVE_HIGH>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
panel0_in: endpoint {
remote-endpoint = <&dsi0_out>;
};
};
port@1 {
reg = <1>;
panel1_in: endpoint {
remote-endpoint = <&dsi1_out>;
};
};
};
};
};
