* tag 'omap-for-v3.16/prcm-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP4: PRCM: remove references to cm-regbits-44xx.h from PRCM core files
  ARM: OMAP3/4: PRM: add support of late_init call to prm_ll_ops
  ARM: OMAP3/OMAP4: PRM: add prm_features flags and add IO wakeup under it
  ARM: OMAP3/4: PRM: provide io chain reconfig function through irq setup
  ARM: OMAP2+: PRM: remove unnecessary cpu_is_XXX calls from prm_init / exit
  ARM: OMAP2+: PRCM: cleanup some header includes
  ARM: OMAP4: CM: use cm_base* in register address calculations
