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
