Merge tag 'msm-dt-for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm into next/dt

From David Brown:

These patches migrate both the 8660 and 8960 targets on msm to be
devicetree only.  This also sets most of the frame in place necessary
to build both targets into the same image.

There's a couple of cleanups in here that are kept in this series
because they are intimately tied to the changes necessary to support
the devicetree conversions.

The timer code relies on #defines from mach/iomap.h, cpu_is_*()
checks, and a global irq #define. All this makes this file
impossible to compile in a mult-target build. Therefore, make a
sys_timer struct for each SoC so that machine descriptors can
reference the correct timer. Then go through and replace all the
defines with raw values that are passed to a common
initialization function.

This paves the way to adding DT support to this code as well as
allows us to compile this file on multiple targets at the same
time.

With 3.4 kernel the static iomappings can be shared with the ioremap
mappings. If ioremap is called with an address for which a static
mapping already exists, then that mapping should be used instead
of creating a new one.

However, the MT_DEVICE_NONSHARED flag prevents this. Hence, get rid
of this flag. Some targets (7X00) that require the static iomappings
to be NONSHARED use the MSM_DEVICE_TYPE and MSM_CHIP_DEVICE_TYPE macros.

A previous patch[1] added code to initialize an FPGA register on the
8660 "SURF" development platform.  Since this development platform is
not widely available, and there is now a more available device "the
Dragonboard" based on the same core SOC, this change was dropped.

However, the DT code kept a lingering call to this FPGA init function.
Remove it.

It really becomes an maintenance issue that every time a device needs
to look up (clk_get) a clock we have to patch kernel clock file to call
clk_register_clkdev for that clock.

Since clock DT support which is meant to resolve clock lookup in device
tree is in place, the patch moves imx6q client devices' clock lookup
over to device tree, so that any new lookup to be added at later time
can just get done in DT instead of kernel.
