Merge branch 'omap-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6
* 'omap-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6: (47 commits)
OMAP clock: use debugfs_remove_recursive() for rewinding
OMAP2/3/4 core: create omap_device layer
OMAP: omap_hwmod: call omap_hwmod init at boot; create interconnects
OMAP2/3/4: create omap_hwmod layer
OMAP2/3 board-*.c files: read bootloader configuration earlier
OMAP2/3/4 PRCM: add module IDLEST wait code
OMAP2/3 PM: create the OMAP PM interface and add a default OMAP PM no-op layer
OMAP3 clock: remove superfluous calls to omap2_init_clk_clkdm
OMAP clock: associate MPU clocks with the mpu_clkdm
OMAP3 clock: Fixed processing of bootarg 'mpurate'
OMAP: SDRC: Add several new register definitions
OMAP: powerdomain: Fix overflow when doing powerdomain deps lookups.
OMAP: PM: Added suspend target state control to debugfs for OMAP3
OMAP: PM debug: Add PRCM register dump support
OMAP: PM debug: make powerdomains use PM-debug counters
OMAP: PM: Add pm-debug counters
OMAP: PM: Add closures to clkdm_for_each and pwrdm_for_each.
OMAP: PM: Hook into PM counters
OMAP: PM counter infrastructure.
OMAP3: PM: fix lockdep warning caused by omap3_pm_init
