But think about one pretty important distinction - what videobuf implementation is your driver going to use? Are you going to support scatter-gather or only contiguous buffers? If SG - the only such example in the mainline is pxa_camera.c. If contiguous - feel free to use any one of the rest. Further, mx3_camera uses the dmaengine API, others don't. Hope, this will simplify your choice a bit;) Thanks Guennadi > Regards, > Sedji > > Le 4/29/2010 6:35 PM, Guennadi Liakhovetski a écrit : > > Hi Sedji > > > > On Thu, 29 Apr 2010, Sedji Gaouaou wrote: > > > > > Hi, > > > > > > I need to re-work my driver so I could commit it to the community. > > > Is there a git tree that I can use? > > > > Nice to hear that!
