Merge branch 'for-linus' of git://gitorious.org/linux-omap-dss2/linux
* 'for-linus' of git://gitorious.org/linux-omap-dss2/linux: OMAP: DSS2: don't power off a panel twice OMAP: DSS2: OMAPFB: Allow usage of def_vrfb only for omap2,3 OMAP: DSS2: OMAPFB: make VRFB depends on OMAP2,3 OMAP: DSS2: OMAPFB: Allow FB_OMAP2 to build without VRFB arm/omap: simplify conditional OMAP: DSS2: DSI: Remove extra iounmap in error path OMAP: DSS2: Use dss_features framework on DSS2 code OMAP: DSS2: Introduce dss_features files video/omap: remove mux.h include ARM: omap/fb: move get_fbmem_region() to .init.text ARM: omap/fb: move omapfb_reserve_sram to .init.text ARM: omap/fb: move omap_init_fb to .init.text OMAP: DSS2: OMAPFB: swap front and back porches for both hsync and vsync OMAP: DSS2: make filter coefficient tables human readable OMAP: DSS2: Add SPI dependency to Kconfig of ACX565AKM panel
