The minimum width and height for VPE input/output was kept as 128
pixels. VPE doesn't have a constraint on the image height, it requires
the image width to be atleast 16 bytes.

"16 bytes" - shouldn't it be pixels? (also "at least" :) )
I can correct it when applying the patch if the above is the case.

VPDMA IP requires the line stride of the input/output images to be at least 16 bytes in total.

This can safely result in a minimum width of 16 pixels(NV12 has the least bpp with 1 byte per pixel). But we don't really have any need to support such small image resolutions. So I picked up 32x32 as the minimum size, and tested VPE with that.

Thanks,
Archit
