Merge tag 'omap-fixes-a-for-3.5rc' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into fixes

From Paul Walmsley (as per Tony Lindgren's request):
 "Some uncontroversial OMAP clock, hwmod, and compiler warning fixes for 3.5-rc"

* tag 'omap-fixes-a-for-3.5rc' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending:
  ARM: OMAP4: hwmod data: Force HDMI in no-idle while enabled
  ARM: OMAP2+: mux: fix sparse warning
  ARM: OMAP2+: CM: increase the module disable timeout
  ARM: OMAP4: clock data: add clockdomains for clocks used as main clocks
  ARM: OMAP4: hwmod data: fix 32k sync timer idle modes
  ARM: OMAP4+: hwmod: fix issue causing IPs not going back to Smart-Standby
  ARM: OMAP: PM: Lock clocks list while generating summary
