Merge tag 'omap-for-v3.13/fixes-for-merge-window-take2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

Few clock fixes, a runtime PM fix, and pinctrl-single fix along
with few other fixes that popped up during the merge window.

* tag 'omap-for-v3.13/fixes-for-merge-window-take2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP2+: Fix build for dra7xx without omap4 and 5
  ARM: OMAP2+: omap_device: maintain sane runtime pm status around suspend/resume
  doc: devicetree: Add bindings documentation for omap-des driver
  ARM: dts: doc: Document missing compatible property for omap-sham driver
  ARM: OMAP3: Beagle: fix return value check in beagle_opp_init()
  ARM: OMAP: devicetree: fix SPI node compatible property syntax items
  pinctrl: single: call pcs_soc->rearm() whenever IRQ mask is changed
  ARM: OMAP2+: smsc911x: fix return value check in gpmc_smsc911x_init()
  + sync with newer trunk
