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()
