-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 = <&reg_vcc5v0>;
-		enable-gpios = <&pio 7 8 GPIO_ACTIVE_HIGH>;
-		backlight = <&backlight>;
-	};
-};
