Merge branch 'cleanup-pm' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup 

* 'cleanup-pm' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP2+: PM: share some suspend-related functions across OMAP2, 3, 4
  ARM: OMAP2+: omap_device: call all suspend, resume callbacks when OMAP_DEVICE_NO_IDLE_ON_SUSPEND is set
  ARM: OMAP: omap_device: remove omap_device_parent
  ARM: OMAP2+: PM debug: fix the use of debugfs_create_* API
  ARM: OMAP2+: PM: share clkdms_setup() across OMAP2, 3, 4
  ARM: OMAP2+: PM: clean up omap_set_pwrdm_state()
  ARM: OMAP3: PM: remove superfluous calls to pwrdm_clear_all_prev_pwrst()
  ARM: OMAP: convert omap_device_build() and callers to __init
  ARM: OMAP2+: Mark omap_hsmmc_init and omap_mux related functions as __init
  ARM: OMAP2+: Split omap2_hsmmc_init() to properly support I2C GPIO pins
  ARM: OMAP: omap_device: Expose omap_device_{alloc, delete, register}
  ARM: OMAP: Fix build error when mmc_omap is built as module
  ARM: OMAP: Fix kernel panic with HSMMC when twl4030_gpio is a module
