Hi Phillipp It sounds like you need me to test a new kernel build with these patches now?
I'm new round here so could you please give me the git commands to check out your patches / tree as well as any kernel config options I'll need to ensure are enabled for full imxdrm / SABRE Lite support. I started moving house yesterday and that continues today and tomorrow so the soonest I am going to be able to build and test a new kernel will be Wednesday but Thursday or this upcoming weekend is more likely.
