Hi Mark
Thank you for your help. I see, I will start moving it, but I need sample code for it. Who is using DPCM ?
Nobody in tree unfortunately. The TI OMAP and Qualcomm production kernels use it as do some of the newer Intel Haswell chips but all of that is out of tree. There's also the work Russell has been doing for Kirkwood but I don't think he posted the finished version to the list yet (he's waiting for some fixes from Liam which will hopefully come soon).
Hmm... OK I understood. Do you think it is possible to get these out-of-tree codes from somewhere/somehow ? I can work for DPCM support for our driver, but it is very difficult for me without sample code...
If I could get sample code, and I finished my current task, I will start DPCM support. is it OK ?
