Merge tag 'omap-for-v3.8/cleanup-prcm-part1-take2-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/headers
From Paul Walmsley <paul@pwsan.com> via Tony Lindgren:
The first set of OMAP PRM/CM-related cleanup patches for 3.8.
Prepares for the future move of the PRM/CM code to drivers/. Also
includes some prcm.[ch] cleanup patches from the WDTIMER cleanup
series that don't need external acks.
* tag 'omap-for-v3.8/cleanup-prcm-part1-take2-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: OMAP2+: PRM: create PRM reset source API for the watchdog timer driver
ARM: OMAP1: create read_reset_sources() function (for initial use by watchdog)
ARM: OMAP2+: CM: prepare for use of cm_ll_data function pointers
ARM: OMAP2+: PRM: prepare for use of prm_ll_data function pointers
ARM: OMAP2/3: clockdomain/PRM/CM: move the low-level clockdomain functions into PRM/CM
ARM: OMAP2+: CM/hwmod: split CM functions into OMAP2, OMAP3-specific files
ARM: OMAP2+: powerdomain/PRM: move the low-level powerdomain functions into PRM
ARM: OMAP2+: PRM: split PRM functions into OMAP2, OMAP3-specific files
ARM: OMAP2+: PRM: remove PRM weak functions
