Without the PM QoS parameter, there appears to be no clean way (in my opinion) to get requests from multiple drivers to increase the system bus performance (which is possible in MSM chipsets). Adding this parameter would also allow me to delete some code in the Android specific implementation of arch/arm/mach-msm/clock.c that's unnecessarily mach-msm specific and use the generic clkdev library that's available for the ARM architecture. This would in turn allow me to upstream (after further clean up) more code that's currently present only in the kernel used in Android.
