Subject: [PATCH V6 00/15] ARM: OMAP3+: support cpufreq-cpu0 for device tree boot

Hi,

The series is based on Tero's V8 of patches[1] - enables the use of
cpufreq-cpu0 generic driver for all OMAP and related derivatives.

I will stop copy pasting the series complete history and point at [2].

Main changes since V5:
- no more clock driver as part of this series[3] - instead depend on clock
  conversion[1].
- added DRA7/OMAP5

Notes:
- i have organized the series such that
  * patches 1-6 could go to Tony/Kevin/Paul trees
  * Dts series is further split up given continued uncertaininty of v8 clock dts
    nodes into two sets
	- patches 7-10 are based on Benoit's for_13/dts branch and can apply
	  there independently.
	- patches 11-15 are dependent on 7-10 patches + clock nodes being
	  available.
- Given the uncertainity with clock nodes, I recommend we get rid of the
  dependencies (1-10) and decide on clock nodes once the story is clearer.
	- if we feel I should squash up clock nodes 9+14, 10+15, I can do that
	  as well.

Series is built on top of V3.12-rc4 + the following maintainer tree merges
	git://git.kernel.org/pub/scm/linux/kernel/git/bcousson/linux-omap-dt for_3.13/dts
	git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap tag 'fixes-against-v3.12-rc3-take2' and omap-for-v3.13/soc branch
