Binding for Olimex Ltd. LCD-OLinuXino bridge panel.
|
||||
|
||||
This device can be used as bridge between a host controller and LCD panels.
|
||||
Currently supported LCDs are:
|
||||
- LCD-OLinuXino-4.3TS
|
||||
- LCD-OLinuXino-5
|
||||
- LCD-OLinuXino-7
|
||||
- LCD-OLinuXino-10
|
||||
|
||||
The panel itself contains:
|
||||
- AT24C16C EEPROM holding panel identification and timing requirements
|
||||
- AR1021 resistive touch screen controller (optional)
|
||||
- FT5x6 capacitive touch screnn controller (optional)
|
||||
- GT911/GT928 capacitive touch screen controller (optional)
|
||||
|
||||
The above chips share same I2C bus. The EEPROM is factory preprogrammed with
|
||||
device information (id, serial, etc.) and timing requirements.
|
||||
|
||||
Touchscreen bingings can be found in these files:
|
||||
- input/touchscreen/goodix.txt
|
||||
- input/touchscreen/edt-ft5x06.txt
|
||||
- input/touchscreen/ar1021.txt
|
||||
|
||||
Required properties:
|
||||
- compatible: should be "olimex,lcd-olinuxino"
|
||||
- reg: address of the configuration EEPROM, should be <0x50>
|
||||
- power-supply: phandle of the regulator that provides the supply voltage
|
||||
|
||||
Optional properties:
|
||||
- enable-gpios: GPIO pin to enable or disable the panel
|
||||
- backlight: phandle of the backlight device attacked to the panel
|
||||
|
||||
Example:
|
||||
&i2c2 {
|
||||
panel@50 {
|
||||
compatible = "olimex,lcd-olinuxino";
|
||||
reg = <0x50>;
|
||||
power-supply = <®_vcc5v0>;
|
||||
enable-gpios = <&pio 7 8 GPIO_ACTIVE_HIGH>;
|
||||
backlight = <&backlight>;
|
||||
};
|
||||
};
