+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 {

 TPO TPG110 Panel
 ================
 
-This binding builds on the DPI bindings, adding a few properties
-as a superset of a DPI. See panel-dpi.txt for the required DPI
-bindings.
+This panel driver is a component that acts as an intermediary
+between an RGB output and a variety of panels. The panel
+driver is strapped up in electronics to the desired resolution
+and other properties, and has a control interface over 3WIRE
+SPI. By talking to the TPG110 over SPI, the strapped properties
+can be discovered and the hardware is therefore mostly
+self-describing.
+
+       +--------+
+SPI -> |  TPO   | -> physical display
+RGB -> | TPG110 |
+       +--------+
+
+If some electrical strap or alternate resolution is desired,
+this can be set up by taking software control of the display
+over the SPI interface. The interface can also adjust
+for properties of the display such as gamma correction and
+certain electrical driving levels.
+
+The TPG110 does not know the physical dimensions of the panel
+connected, so this needs to be specified in the device tree.
+
+It requires a GPIO line for control of its reset line.
+
+The serial protocol has line names that resemble I2C but the
+protocol is not I2C but 3WIRE SPI.
 
 Required properties:
-- compatible : "tpo,tpg110"
+- compatible : one of:
+  "ste,nomadik-nhk15-display", "tpo,tpg110"
+  "tpo,tpg110"
 - grestb-gpios : panel reset GPIO
-- scen-gpios : serial control enable GPIO
-- scl-gpios : serial control clock line GPIO
-- sda-gpios : serial control data line GPIO
+- width-mm : see display/panel/panel-common.txt
+- height-mm : see display/panel/panel-common.txt
+
+The device needs to be a child of an SPI bus, see
+spi/spi-bus.txt. The SPI child must set the following
+properties:
+- spi-3wire
+- spi-max-frequency = <3000000>;
+as these are characteristics of this device.
 
-Required nodes:
-- Video port for DPI input, see panel-dpi.txt
-- Panel timing for DPI setup, see panel-dpi.txt
+The device node can contain one 'port' child node with one child
+'endpoint' node, according to the bindings defined in
+media/video-interfaces.txt. This node should describe panel's video bus.
