 * This register controls the anti-aliasing mode of the Tiling Co-Processor, independent control is

 * This register needs to be set based on the ISP Samples Per Pixel a core supports.
 *
 * When ISP Samples Per Pixel = 1:
 * 2xmsaa is achieved by enabling Y - TE does AA on Y plane only
 * 4xmsaa is achieved by enabling Y and X - TE does AA on X and Y plane
 * 8xmsaa not supported by XE cores
 *
 * When ISP Samples Per Pixel = 2:
 * 2xmsaa is achieved by enabling X2 - does not affect TE
 * 4xmsaa is achieved by enabling Y and X2 - TE does AA on Y plane only
 * 8xmsaa is achieved by enabling Y, X and X2 - TE does AA on X and Y plane
 * 8xmsaa not supported by XE cores
 *
 * When ISP Samples Per Pixel = 4:
 * 2xmsaa is achieved by enabling X2 - does not affect TE
 * 4xmsaa is achieved by enabling Y2 and X2 - TE does AA on Y plane only
 * 8xmsaa not supported by XE cores
