80be8aa31e ARM i.MX6: fix ldb_di_sel mux
This adds the mmdc_ch1 as a possible parent for the ldb_di clk.
According to the datasheet, this clock can be selected at this mux.

e3372474cf ARM: imx: include common.h rather than mach/common.h
Rename mach-imx/include/mach/common.h to mach-imx/common.h and update
all users to include common.h rather than mach/common.h.

It also removes an unneeded inclusion to common.h in
mach-imx/devices/devices.c.

cc7887c3b1 ARM: imx6q: use pll2_pfd2_396m as the enfc_sel's parent
The gpmi-nand driver can support the ONFI nand chip's EDO (extra data out)
mode in the asynchrounous mode. In the asynchrounous mode 5, the gpmi
needs 100MHz clock for the IO. But with the pll2_pfd0_352m, we can not
get the 100MHz clock.

So choose pll2_pfd2_396m as enfc_sel's parent.

73f5ae3132 imx-clk-dt-lookup
It replaces the clk_register_clkdev in imx6q clock driver with DT
 lookup.  It depends on Mike's clk-3.7 branch.
 
 When it gets merged together with imx-dt-3.7, there is a trivial
 conflict on arch/arm/boot/dts/imx6q.dtsi.

0e87e0436c ARM: imx6q: replace clk_register_clkdev with clock DT lookup
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.

16339464c5 ARM i.MX6q: Add virtual 1/3.5 dividers in the LDB clock path
The ldb_di[01]_podf is implemented as a clk-divider that
divides by 1 or 2. In reality, the ldb_di[01]_ipu_div
dividers divide by either 3.5 or 7. Adding a fixed factor
of 1/3.5 fixes their children's clock rates.

This should probably be converted to rate table based dividers,
once available.

4f2d658b2f arm-soc: device tree description updates
This branch contains two kinds of updates: Some platforms in the process
 of getting converted to device tree based booting, and the platform
 specific patches necessary for that are included here. Other platforms
 are already converted, so we just need to update the actual device
 tree source files and the binding documents to add support for new board
 and new drivers.
 In the future we will probably separate those into two branches, and
 in the long run, the plan is to move the device tree source files out
 of the kernel repository, but that has to wait until we have completed
 a much larger portion of the binding documents.
