This series converts mach-davinci to use the common clock framework.
The series works like this, the first 3 patches fix some issues with the clock
drivers that have already been accepted into the mainline kernel.
Then, starting with "ARM: davinci: pass clock as parameter to
davinci_timer_init()", we get the mach code ready for the switch by adding the
code needed for the new clock drivers and adding #ifndef CONFIG_COMMON_CLK
around the legacy clocks so that we can switch easily between the old and the
new.
"ARM: davinci: switch to common clock framework" actually flips the switch
to start using the new clock drivers. Then the next 8 patches remove all
of the old clock code.
The final four patches add device tree clock support to the one SoC that
supports it.
This series has been tested on TI OMAP-L138 LCDK (both device tree and legacy
board file).
I am not sure if I did something wrong, but I attempted to build and I
wasn't able to boot the da850-evm.dtb your repo common-clk-v11,
however the legacy board file boot was OK.
make davinci_all_defconfig ARCH=arm
make zImage modules da850-evm.dtb ARCH=arm CROSS_COMPILE=arm-linux- -j8

If you have some suggestions, I am try them as I get time.
As with each revision of this series, I have included debugging tips
in the cover letter, e.g. earlyprink and not disabling unused clocks.
