1Truly model NT35597 DSI display driver 2 3The Truly NT35597 is a generic display driver, currently only configured 4for use in the 2K display on the Qualcomm SDM845 MTP board. 5 6Required 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 25 26Example: 27 28 dsi@ae94000 { 29 panel@0 { 30 compatible = "truly,nt35597-2K-display"; 31 reg = <0>; 32 vdda-supply = <&pm8998_l14>; 33 vdispp-supply = <&lab_regulator>; 34 vdispn-supply = <&ibb_regulator>; 35 pinctrl-names = "default", "suspend"; 36 pinctrl-0 = <&dpu_dsi_active>; 37 pinctrl-1 = <&dpu_dsi_suspend>; 38 39 reset-gpios = <&tlmm 6 GPIO_ACTIVE_LOW>; 40 mode-gpios = <&tlmm 52 GPIO_ACTIVE_HIGH>; 41 ports { 42 #address-cells = <1>; 43 #size-cells = <0>; 44 port@0 { 45 reg = <0>; 46 panel0_in: endpoint { 47 remote-endpoint = <&dsi0_out>; 48 }; 49 }; 50 51 port@1 { 52 reg = <1>; 53 panel1_in: endpoint { 54 remote-endpoint = <&dsi1_out>; 55 }; 56 }; 57 }; 58 }; 59 }; 60
