 As this depends on omap-devel-hwmod-data-for-v3.5 and causes merge
 conflict with omap-fixes-non-critical-for-v3.5, this branch is based

Merge tag 'omap-cleanup-devices-for-v3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup2

Changes to split plat-omap/devices.c into mach-omap1 and mach-omap2
except for the RNG driver that will be done later on.

As this depends on omap-devel-hwmod-data-for-v3.5 and causes merge
conflict with omap-fixes-non-critical-for-v3.5, this branch is based
on merge of the two.
