| 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>; |
| }; |
| }; |
