This patch series does clean up of Kevin Hilman's PM tree
so that the earlier Smartreflex series against lo-master can
be applied seamlessly. This patch sereis also does some
smartreflex related code changes in the cpuidle and dvfs
code which exists only in the pm tree and not on lo-master.

This patch series has been tested in conjunction with the
the Smartreflex series posted against the lo-master on
OMAP3430 SDP, OMAP3630SDP and ZOOM3 using omap3_pm_defconfig.

Thara Gopinath (4):
  OMAP3: PM: Cleaning up of smartreflex code.
  OMAP3: PM: Disabling Smartreflex across both frequency and voltage
    scaling during DVFS.
  OMAP3: PM: Removing voltage related code from the generic pm code.
  OMAP3: PM: Enabling Smartreflex Class 3 driver by default in pm
    defconfig

This patch removes smartreflex driver and other associated code so
that the patch series posted against LO for adding smartreflex support
can be applied seamlessly on linux-omap-pm . Unfortunately even with
this patch the code changes in arch/arm/mach-omap2/pm-debug.c in the
LO smartreflex series have to be manually applied to this tree.

This patch disables smartreflex across both frequency and voltage
scaling instead of just across voltage scaling as before.
This is the hardware recommended practice.
This bug was first reported and solved on Nokia N900
code base by Nishanth Menon and Paul Walmsley.

This patch also does some changes in SRF to adapt to the new smartreflex
and voltage driver.

Now there is a voltage driver to handle all voltage
specific code. This patch removes all voltage specific code
from generic pm code so that the new voltage driver can
function properly. Also this patch renames the smartreflex
API's used in the generic pm code as per the new
smartreflex driver.

This series should no longer be necessary as your latest SR series is
part of the PM branch (as pm-sr branch.)

This one I've added to the pm-srf branch.

And I've updatd omap3_pm_defconfig with this one.

Thanks,

Kevin
