[PATCH v7 1/2] video: ARM CLCD: Add DT support

+* 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
+
+- clocks-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:
+
+- arm,pl11x,framebuffer-base: a pair of two 32-bit values, address and size,
+       defining the framebuffer that must be used; 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
+
+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; 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>;
