Hello,
This small patch series adds support for two addition YUV 4:4:4 packed
formats. There's nothing very special, but I've marked the patch series
as RFC as the driver which will use this (NXP i.MX8 ISI) is still work
in progress. Review of the pixel formats would however be already
appreciated.

They are identical indeed. I think it's a historical mistake, AYUV32 has likely been added without realizing YUV32 was already providing the same format. V4L2_PIX_FMT_YUV32 is used by ivtv, exynos-gsc, vivid and the staging IMX drivers. I think it would make sense to deprecate it so that new drivers will exaplicitly pick either the A or the X variant.
