Yeah, I had the same problem and applied a rather "harsh solution" : amputation :) I'll add back the cropping code later. > It is of course possible to do given enough time, but I don't think it is worth it. > > So instead I am going for plan B: convert all other soc-camera drivers to 'regular' > drivers so in the end soc-camera is only used by the sh driver.

Of course I will, I committed to. As long as I feel having feedback on the other end I'll push until the conversion is complete, and beyond (ie. adding back lost functionality and "beautifying the design"). It's very refreshing for my brain to do this :) I'll have more spare time in the comming monthes also, and as I'm doing this on my spare time, that means more hours to dedicate to pxa maintainance.
