No, this cannot work. That kernel patch requires media-controller and omap3isp, so, it is based on the omap3isp branch of the development tree by Laurent Pinchart: git://linuxtv.org/pinchartl/media.git But that tree has been rebased since then, so, I wouldn't expect that patch to apply cleanly, porting it to the current kernel would require a non-zero development effort. > I suppose that kernel version is wrong or missing previous patches > (see result at the end). > I have to make it work: MT9P031 SoC camera module on Beagleboard Xm. > Could somebody help me? Where/how can I get the right kernel version? I'll send you a tarball of those "old" patches off-list.
