Thanks for the info. It's this sort of thing that isn't clearly
documented anywhere, and until I'm REALLY familiar with the kernel knowing
where to look is a challenge.
A follow on question though. I've looked at the patch and it seems to be
just adding 6 lines to an existing array in fsl_soc.c. However, I can't
seem to find any array in fsl_soc.c that contains lines that the patch
indicates should already be there (i.e., there's nothing in fsl_soc.c that
has the word "ricoh" in it which the patch indicates it should). Is my
fsl_soc.c already out of date? Will the patch apply? I've got 2.6.22.
