-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.

-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>;
-};
