Hmm, I did a deeper look into this code. Why - for example - does the file
mx31ads-wm8753.c does the job of the BSP file? Why it registers devices? For
my board I want to register platform_devices only in
arc/arm/mach-mx2/pcm038.c. Nowhere else. If there is some glue required to
bring components together, IMHO also arc/arm/mach-mx2/pcm038.c is the correct
place to do so. Why you did it in sound/ ? If you do it in sound/ , you
always need two locations to maintain. On in the arch/, one in sound/ .
