MLK-19274: drm: imx: dcss: add rotation functionality
This patch will allow userspace to rotate planes by setting the
'rotation' property. Generally, 0 and 180 rotations are allowed for
pretty much all 8-bit xRGB and 2-plane YUV420 formats. 90/270 rotations
can be performed only for non-compressed tiled GPU xRGB formats. Tiled
YUV420 formats do not allow rotations at all because these formats need
DTRC for de-tiling and DTRC has no rotation support.
For more info, consult the DPR Features chapter in the reference manual.
Test example:
modetest -M imx-drm -w 27:rotation:4 -w 32:rotation:33 -w 27:alpha:30 -s
42@31:3840x2160-60@XR24 -P 32@31:3840x2160@NV21
The above will perform:
* 180 degree rotation of primary plane (XR24);
* vertical flip of first overlay plane (rotate-0 | reflect-y);
* set primary plane alpha to 30;
