This panel driver supports both single DSI and dual DSI. However, this patch series supports only dual DSI. Changes in v6: - Change the compatible string to indicate the reference board and the panel - Remove the display timing node Signed-off-by: Abhinav Kumar --- .../devicetree/bindings/display/truly,nt35597.txt | 55 ++++++++++++++++++++++ 1 file changed, 55 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/truly,nt35597.txt diff --git a/Documentation/devicetree/bindings/display/truly,nt35597.txt b/Documentation/devicetree/bindings/display/truly,nt35597.txt new file mode 100644 index 0000000..68960a6 --- /dev/null +++ b/Documentation/devicetree/bindings/display/truly,nt35597.txt @@ -0,0 +1,55 @@ +Truly model NT35597 1440x2560 DSI Panel + +Required properties: +- compatible: should be "qcom,sdm845-mtp-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 +- 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.
