Simple display panel
|
====================
|
|
panel node
|
----------
|
|
Required properties:
|
- compatible: Should contain one of the following:
|
- "simple-panel": for common simple panel
|
- "simple-panel-dsi": for common simple dsi panel
|
- "vendor,panel": for vendor specific panel
|
- power-supply: See panel-common.txt
|
|
Optional properties:
|
- vsp-supply: positive voltage supply
|
- vsn-supply: negative voltage supply
|
- ddc-i2c-bus: phandle of an I2C controller used for DDC EDID probing
|
- enable-gpios: GPIO pin to enable or disable the panel
|
- reset-gpios: GPIO pin to reset the panel
|
- backlight: phandle of the backlight device attached to the panel
|
- prepare-delay-ms: the time (in milliseconds) that it takes for the panel to
|
become ready and start receiving video data
|
- enable-delay-ms: the time (in milliseconds) that it takes for the panel to
|
display the first valid frame after starting to receive
|
video data
|
- disable-delay-ms: the time (in milliseconds) that it takes for the panel to
|
turn the display off (no content is visible)
|
- unprepare-delay-ms: the time (in milliseconds) that it takes for the panel
|
to power itself down completely
|
- reset-delay-ms: the time (in milliseconds) that it takes for the panel to
|
reset itself completely
|
- init-delay-ms: the time (in milliseconds) that it takes for the panel to
|
send init command sequence after reset deassert
|
- width-mm: width (in millimeters) of the panel's active display area
|
- height-mm: height (in millimeters) of the panel's active display area
|
- bpc: bits per color/component
|
- bus-format: Pixel data format on the wire
|
|
- dsi,lanes: number of active data lanes
|
- dsi,format: pixel format for video mode
|
- dsi,flags: DSI operation mode related flags
|
- panel-init-sequence:
|
- panel-exit-sequence:
|
A byte stream formed by simple multiple dcs packets.
|
byte 0: dcs data type
|
byte 1: wait number of specified ms after dcs command transmitted
|
byte 2: packet payload length
|
byte 3 and beyond: number byte of payload
|
|
- power-invert: power invert control
|
- rockchip,cmd-type: default is DSI cmd, or "spi", "mcu" cmd type
|
- spi-sdi: spi init panel for spi-sdi io
|
- spi-scl: spi init panel for spi-scl io
|
- spi-cs: spi init pael for spi-cs io
|
|
Example:
|
|
panel: panel {
|
compatible = "cptt,claa101wb01";
|
ddc-i2c-bus = <&panelddc>;
|
|
power-supply = <&vdd_pnl_reg>;
|
enable-gpios = <&gpio 90 0>;
|
|
backlight = <&backlight>;
|
};
