| 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 |
| 25 | |
| 26 | Example: |

| 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 { |

| 49 | }; |
| 50 | |
| 51 | port@1 { |
| 52 | reg = <1>; |
| 53 | panel1_in: endpoint { |
| 54 | remote-endpoint = <&dsi1_out>; |
| 55 | }; |
| 56 | }; |
| 57 | }; |
