Tianma Micro-electronics TM070RVHG71 7.0" WXGA TFT LCD panel
Required properties:
- compatible: should be "tianma,tm070rvhg71"
- power-supply: single regulator to provide the supply voltage
- backlight: phandle of the backlight device attached to the panel
Required nodes:
- port: LVDS port mapping to connect this display
This panel needs single power supply voltage. Its backlight is conntrolled
via PWM signal.
Example:
--------
Example device-tree definition when connected to iMX6Q based board
panel: panel-lvds0 {
compatible = "tianma,tm070rvhg71";
backlight = <&backlight_lvds>;
power-supply = <&reg_lvds>;
port {
panel_in_lvds0: endpoint {
remote-endpoint = <&lvds0_out>;
};
};
};
