+* ARM PrimeCell Color LCD Controller PL110/PL111
+
+See also Documentation/devicetree/bindings/arm/primecell.txt
+
+Required properties:
+
+- compatible: must be one of:
+ "arm,pl110", "arm,primecell"
+ "arm,pl111", "arm,primecell"
+
+- reg: base address and size of the control registers block
+
+- interrupt-names: either the single entry "combined" representing a
+ combined interrupt output (CLCDINTR), or the four entries
+ "mbe", "vcomp", "lnbu", "fuf" representing the individual
+ CLCDMBEINTR, CLCDVCOMPINTR, CLCDLNBUINTR, CLCDFUFINTR interrupts
+
+- interrupts: contains an interrupt specifier for each entry in
+ interrupt-names
+
+- clock-names: should contain "clcdclk" and "apb_pclk"
+
+- clocks: contains phandle and clock specifier pairs for the entries
+ in the clock-names property. See
+ Documentation/devicetree/binding/clock/clock-bindings.txt
+
+Optional properties:
+
+- memory-region: phandle to a node describing memory (see
+ Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt)
+ to be used for the framebuffer; if not present, the framebuffer
+ may be located anywhere in the memory
+
+- max-memory-bandwidth: maximum bandwidth in bytes per second that the
+ cell's memory interface can handle; if not present, the memory
+ interface is fast enough to handle all possible video modes
+
+Required sub-nodes:
+
+- port: describes LCD panel signals, following the common binding
+ for video transmitter interfaces; see
+ Documentation/devicetree/bindings/media/video-interfaces.txt;
+ when it is a TFT panel, the port's endpoint must define the
+ following property:
+
+ - arm,pl11x,tft-r0g0b0-pads: an array of three 32-bit values,
+ defining the way CLD pads are wired up; first value
+ contains index of the "CLD" external pin (pad) used
+ as R0 (first bit of the red component), second value
+ index of the pad used as G0, third value index of the
+ pad used as B0, see also "LCD panel signal multiplexing
+ details" paragraphs in the PL110/PL111 Technical
+ Reference Manuals; this implicitly defines available
+ color modes, for example:
+ - PL111 TFT 4:4:4 panel:
+ arm,pl11x,tft-r0g0b0-pads = <4 15 20>;
+ - PL110 TFT (1:)5:5:5 panel:
+ arm,pl11x,tft-r0g0b0-pads = <1 7 13>;
+ - PL111 TFT (1:)5:5:5 panel:
+ arm,pl11x,tft-r0g0b0-pads = <3 11 19>;
+ - PL111 TFT 5:6:5 panel:
+ arm,pl11x,tft-r0g0b0-pads = <3 10 19>;
+ - PL110 and PL111 TFT 8:8:8 panel:
+ arm,pl11x,tft-r0g0b0-pads = <0 8 16>;
+ - PL110 and PL111 TFT 8:8:8 panel, R & B components swapped:
+ arm,pl11x,tft-r0g0b0-pads = <16 8 0>;
+
+
+Example:
+

+ compatible = "arm,pl111", "arm,primecell";

+* Currus Logic CLPS711X Framebuffer

+Required properties:
+- compatible: Shall contain "cirrus,clps711x-fb".
+- reg : Physical base address and length of the controller's registers +
+ location and size of the framebuffer memory.
+- clocks : phandle + clock specifier pair of the FB reference clock.
+- display : phandle to a display node as described in
+ Documentation/devicetree/bindings/video/display-timing.txt.
+ Additionally, the display node has to define properties:
+ - bits-per-pixel: Bits per pixel.
+ - ac-prescale : LCD AC bias frequency. This frequency is the required
+ AC bias frequency for a given manufacturer's LCD plate.
+ - cmap-invert : Invert the color levels (Optional).

+Optional properties:
+- lcd-supply: Regulator for LCD supply voltage.
