     15  A canvas is a collection of metadata that describes a pixel buffer.
     16  Those metadata include: width, height, phyaddr, wrapping and block mode.
     17  Starting with GXBB the endianness can also be described.
     18
     19  Many IPs within Amlogic SoCs rely on canvas indexes to read/write pixel data
     20  rather than use the phy addresses directly. For instance, this is the case for
     21  the video decoders and the display.
     22
     23  Amlogic SoCs have 256 canvas.
