-TPO TPG110 Panel
-================
-
-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 : one of:
-  "ste,nomadik-nhk15-display", "tpo,tpg110"
-  "tpo,tpg110"
-- grestb-gpios : panel reset 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.
-
-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.
-
-Example
--------
-
-panel: display@0 {
-	compatible = "tpo,tpg110";
-	reg = <0>;
-	spi-3wire;
-	/* 320 ns min period ~= 3 MHz */
-	spi-max-frequency = <3000000>;
-	/* Width and height from data sheet */
-	width-mm = <116>;
-	height-mm = <87>;
-	grestb-gpios = <&foo_gpio 5 GPIO_ACTIVE_LOW>;
-	backlight = <&bl>;
-
-	port {
-		nomadik_clcd_panel: endpoint {
-			remote-endpoint = <&foo>;
