This patch depends on "genalloc: add a global pool list, allow to find pools by phys address", which provides the of_get_named_gen_pool function.

Your commit log doesn't mention that at all, and when I see things like that, I predict allyesconfig build failures, unless there is a similar dependency elsewhere that isn't visible in just the context of this patch alone. P.iram_alloc and iram_free are i.MX specific wrappers around gen_pool_alloc and gen_pool_free, located in <mach/iram.h>. Those were responsible for the dependency in the first place.So when I do an allyesconfig for sparc, or parisc or alpha, and VIDEO_CODA gets selected, it will build just fine then?
I don't know, as I don't have compilers for those available right now. I'd like to know if it doesn't, though. It builds fine on x86 and mips, for example.
My point was that when you remove the ARCH_MXC dep, this probably gets opened up as a viable option to a _lot_ more platforms than you might want it exposed to.
I don't see the problem. Isn't this a good thing? regards Philipp
