[Neil Armstrong]

Now that we have the DT validation in place, let's convert the device tree
bindings for the Amlogic Canvas over to a YAML schemas.

-Amlogic Canvas
-================================
-
-A canvas is a collection of metadata that describes a pixel buffer.
-Those metadata include: width, height, phyaddr, wrapping and block mode.
-Starting with GXBB the endianness can also be described.
-
-Many IPs within Amlogic SoCs rely on canvas indexes to read/write pixel data
-rather than use the phy addresses directly. For instance, this is the case for
-the video decoders and the display.
-
-Amlogic SoCs have 256 canvas.
-
-Device Tree Bindings:
----------------------
-
-Video Lookup Table
---------------------------
-
-Required properties:
-- compatible: has to be one of:
-		- "amlogic,meson8-canvas", "amlogic,canvas" on Meson8
-		- "amlogic,meson8b-canvas", "amlogic,canvas" on Meson8b
-		- "amlogic,meson8m2-canvas", "amlogic,canvas" on Meson8m2
-		- "amlogic,canvas" on GXBB and newer
-- reg: Base physical address and size of the canvas registers.
-
-Example:
-
-canvas: video-lut@48 {
-	compatible = "amlogic,canvas";
-	reg = <0x0 0x48 0x0 0x14>;
-};

one nit-pick below, but I leave it up to Maxime to decide whether it's needed:

personally I prefer "Amlogic Canvas Video Lookup Table" because that's
also what we use (abbreviated as video-lut) for the node name
