Well, anyway, just so everyone is aware: TILER rotation only seems to work correctly for RGB.

For now, until we figure out how to correctly program DSS for YUYV and NV12. :)

You're right about YUYV, the TRM confirms it uses 32-bit mode (as well as that for nv12 the luma uses 8-bit mode and chrome 16-bit mode).

Apart from setting ROTATION correctly in VIDp_ATTRIBUTES it also mentions DOUBLESTRIDE is apparently supposed to be set for NV12 in 0 or 180 degree rotation but not in 90 or 270 degree rotation.
