Subject: [PATCH 00/11] MSM DT based multi-platform support

This patchset allows me to compile and run the DT based MSM
platforms in the multi-platform ARM kernel. This is built on
top of a couple patches I've sent out already (specifically
the debug_ll patch series and the clocksource_of conversion)
as well a patch from Rohit that didn't seem to make it into 
MSM's for-next branch.

There is one problem though, the last two patches cause compile
failures if you turn on MSM's sdcc or USB_OTG driver. It seems
that the sdcc driver depends on the clk_reset() API and the custom
DMA interface provided by mach layers. And the USB_OTG driver depends
on clk_reset.

The simplest solution is to make these two drivers depend on the
non-dt based MSM support so that they can't be compiled in the
multi-platform config. Otherwise, we'll need to replace the clk_reset()
calls with the new reset controller API, but doing that would
require us to convert all MSM platforms over to devicetree or
we'll need to add support to the reset controller API for non-DT based
controllers. Even with that, the sdcc driver uses custom DMA things
so we may need to put that all behind some #ifdef.

Patches are based on David Brown's for-next tree:
