And here's what I can apply later on to get rid of some
ifdeffery.
I'm also planning to move some of the legacy omap hwmod
functionality into proper device drivers, so can generic
pdata for that too.
Cheers,

Subject: [PATCH] ARM: OMAP2+: Simplify auxdata by using the generic match
We can now just use the compatible if there's no need to have
device instance specific auxdata.
