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).
Where was that mentioned? I had a quick look a few days back, and I couldn't find anything conclusive.
Most convincingly in the second NOTE of 10.2.4.6.5 DISPC Predecimation
Well, it's not talking about TILER there. The macro-pixel size is clear, but I was hoping to see a "if you use TILER, you need to use this and that". Or a mention that the macro-pixel size maps directly to the tiler unit sizes (or whatever they are called).
For NV12's luma and chroma 8 and 16 bit units make perfect sense. For YUYV's "two pixels in one" it's quite unclear.
