Hi Philipp, Thanks for this great patchset! Finally we have improved seams with tiled conversions, and relaxed width alignment requirements. Unfortunately this patchset isn't working correctly yet. It breaks tiled conversions with rotation. Trying the following conversion: input: 720x480, UYVY

Hi, we have image conversion code for scaling and colorspace conversion in the IPUv3 base driver for a while. Since the IC hardware can only write up to 1024x1024 pixel buffers, it scales to larger output buffers by splitting the input and output frame into similarly sized tiles. This causes the
