[PATCHv10 00/41] ARM: TI SoC clock DT conversion

> 
> Changes compared to v9:
> - rebased on top of 3.13-rc1
> - modified the low level clk register API to provide SoC specific clk_readl
>   and clk_writel support which can be registered during boot, TI SoC variant
>   uses regmap on low level
> - dropped regmap parameter from clock init calls, instead a helper is used
>   for getting regmap index along with the register offset from DT
> - dropped regmap parameter from clock structs, instead platform specific
>   clk_readl / clk_writel are used to parse reg parameter according to
>   platform, for TI SoC:s, this is encoded as:
>   struct clk_omap_reg {
>     u16 offset; /* register offset */
>     u16 index; /* regmap index */
>   }
> - Nishanth's comments to v9 mostly addressed, except for the CLK_OF_DECLARE
>   tweak which I would actually want some feedback upon, basically the problem
>   is I need to return status from the clk init functions so I can see if
>   -EAGAIN is passed, in which case init will be retried later, maybe some of
>   this can be made generic, like converting all the CLK_OF_DECLARE type
>   functions to return status
> 
> Testing done:
> - omap3-beagle : boot + suspend/resume
> - omap3-beagle-xm : boot (thanks to Nishanth)
> - omap4-panda-es : boot + suspend/resume
> - omap5-uevm : boot
> - dra7-evm : boot
> - am335x-bone : boot

> - full: 3.13-rc1-dt-clks-v10 (should be merged last, contains everything)

FYI, I noticed you still have few hack pathces in this branch that you
should drop before it's pullable.

You can drop "HACK: force enable uart3 rx iochain wakeup" and replace it
with "ARM: dts: Fix omap serial wake-up when booted with device tree" I
posted few days ago. You may also want to use the latest attempt of patch
"of/platform: Fix no irq domain found errors when populating interrupts"
to avoid some new warnings. That way you can test off-idle on omap3 with
DT, but it's best to keep those out of your branch.

Then the "HACK: Makefile: Build a uImage with dtb already appended" you
can just replace with a shell script to leave that one out :)

I pulled these on top of my patches to make mach-omap2 boot in DT only
mode, and there's just a trivial merge conflict with the DT data which
is no problem.

And looks like off-idle keeps working for me on omap3 :) So for the
patches that don't have it yet, please feel free to add:
