Yes, simplifing get soc_camera_format_xlate struct would be great. And yeah, nobody will be working on it in the next 2 monthes. Besides, Hans had expressed interest in having it removed. On my side, as long as the format translation happens, ie. pxa_camera provides a list of formats which is a _superset_ of the sensor formats as today (especially YUV422P, YUYV and its permutations, RGBxxxx), I'll be totally fine with it, even if it was my idea several years ago to have a translation... Let's see what new ideas can provide, new blood etc ... Cheers. -- Robert
