* 'next/devel2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/linux-arm-soc: (47 commits)
  OMAP: Add debugfs node to show the summary of all clocks
  OMAP2+: hwmod: Follow the recommended PRCM module enable sequence
  OMAP2+: clock: allow per-SoC clock init code to prevent clockdomain calls from clock code
  OMAP2+: clockdomain: Add per clkdm lock to prevent concurrent state programming
  OMAP2+: PM: idle clkdms only if already in idle
  OMAP2+: clockdomain: add clkdm_in_hwsup()
  OMAP2+: clockdomain: Add 2 APIs to control clockdomain from hwmod framework
  OMAP: clockdomain: Remove redundant call to pwrdm_wait_transition()
  OMAP4: hwmod: Introduce the module control in hwmod control
  OMAP4: cm: Add two new APIs for modulemode control
  OMAP4: hwmod data: Add modulemode entry in omap_hwmod structure
  OMAP4: hwmod data: Add PRM context register offset
  OMAP4: prm: Remove deprecated functions
  OMAP4: prm: Replace warm reset API with the offset based version
  OMAP4: hwmod: Replace RSTCTRL absolute address with offset macros
  OMAP: hwmod: Wait the idle status to be disabled
  OMAP4: hwmod: Replace CLKCTRL absolute address with offset macros
  OMAP2+: hwmod: Init clkdm field at boot time
  OMAP4: hwmod data: Add clock domain attribute
  OMAP4: clock data: Add missing divider selection for auxclks
