We agree that there is no need for a dump *all* drivers under 
arm/mach-foo in drivers/platform/foo/. The msm bus driver would be added 
under drivers/bus/. But, we still have some drivers which are quite SoC 
specific and not in the general category of the sub-directories present 
under drivers.
As Kumar mentioned earlier -

An example driver would be the means we utilize to communicate memory regions between various HW blocks on the SoC.  So a video/media core driver might need access to a header/functions from the memory region driver.

Would drivers/misc/qcom-* or drivers/misc/qcom/* be a reasonable place to add them ? and the headers could go into include/linux/qcom-*.h
