Merge tag 'omap-for-v3.8/devel-prcm-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/pm2
From Tony Lindgren: omap prcm changes via Paul Walmsley <paul@pwsan.com>: Some miscellaneous OMAP hwmod changes for 3.8, along with a PRM change needed for one of the hwmod patches to function. Basic test logs for this branch on top of Tony's omap-for-v3.8/clock branch at commit 558a0780b0a04862a678f7823215424b4e5501f9 are here: http://www.pwsan.com/omap/testlogs/hwmod_devel_a_3.8/20121121161522/ However, omap-for-v3.8/clock at 558a0780 does not include some fixes that are needed for a successful test. With several reverts, fixes, and workarounds applied, the following test logs were obtained: http://www.pwsan.com/omap/testlogs/TEST_hwmod_devel_a_3.8/20121121162719/ which indicate that the series tests cleanly. * tag 'omap-for-v3.8/devel-prcm-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (49 commits) ARM: OMAP2+: omap_device: Correct resource handling for DT boot ARM: OMAP2+: hwmod: Add possibility to count hwmod resources based on type ARM: OMAP2+: hwmod: Add support for per hwmod/module context lost count ARM: OMAP2+: PRM: initialize some PRM functions early ARM: OMAP2+: clock: Cleanup !CONFIG_COMMON_CLK parts ARM: OMAP2xxx: clock: drop obsolete clock data ARM: OMAP2: clock: Cleanup !CONFIG_COMMON_CLK parts ARM: OMAP3+: DPLL: drop !CONFIG_COMMON_CLK sections ARM: AM33xx: clock: drop obsolete clock data ARM: OMAP3xxx: clk: drop obsolete clock data ARM: OMAP3: clock: Cleanup !CONFIG_COMMON_CLK parts ARM: OMAP44xx: clock: drop obsolete clock data ARM: OMAP4: clock: Cleanup !CONFIG_COMMON_CLK parts ARM: OMAP: hwmod: Cleanup !CONFIG_COMMON_CLK parts ARM: OMAP: clock: Switch to COMMON clk ARM: OMAP2: clock: Add 24xx data using common struct clk ARM: OMAP3: clock: Add 3xxx data using common struct clk ARM: AM33XX: clock: add clock data in common clock format ARM: OMAP4: clock: Add 44xx data using common struct clk ARM: OMAP2+: clock: add OMAP CCF convenience macros to mach-omap2/clock.h ...
