Which tree did you base this on? The media_tree master? Or the mainline kernel? I now have the imx219 detected, but if I try to stream I get this: $ v4l2-ctl --stream-mmap <[ 512.840944] video4linux video0: MW_ACK_DONE syncpt timeout: -11 [ 512.972975] video4linux video0: frame start syncpt timeout: -11 <VIDIOC_DQBUF: failed: Input/output error [ 513.180770] video4linux video0: MW_ACK_DONE syncpt timeout: -11 And then everything hangs and I need to reset. I'm testing with the media_tree master with your patches on top.
