For me the separation between arch/arm/plat-omap/mcbsp.c and
sound/soc/omap/omap-mcbsp.c and board specific control registration
function omap_mcbsp_st_add_controls looks ok.

Set applies well on top of vanilla but the patch 1 doesn't apply on
linux-omap due commit bcbb73c6fe8544bb50cddb8b5df0e2fcbb08b4b0.

I was thinking that it makes sense to base the patch 1 on top of McBSP
register cache patches from Janusz Krzysztofik after Tony applies
them (+ having cache for ST regs). That avoid conflicts in mainline
and makes the sidetone also ready for McBSP context save/restore
functionality.
