From Tony Lindgren:
PM voltage domain clean-up via Kevin Hilman <khilman@linaro.org>:
OMAP: PM: remove requirement for voltage domain data; remove dummy data
* tag 'omap-for-v3.11/pm-voltdomain-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: AM33xx: Remove the unused voltagedomain data
ARM: OMAP2+: Powerdomain: Remove the need to always have a voltdm associated to a pwrdm
Includes an update to Linux 3.10-rc6.
