Merge branch 'omap-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6
* 'omap-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6: (258 commits) omap: zoom: host should not pull up wl1271's irq line arm: plat-omap: iommu: fix request_mem_region() error path OMAP2+: Common CPU DIE ID reading code reads wrong registers for OMAP4430 omap4: mux: Remove duplicate mux modes omap: iovmm: don't check 'da' to set IOVMF_DA_FIXED flag omap: iovmm: disallow mapping NULL address when IOVMF_DA_ANON is set omap2+: mux: Fix compile when CONFIG_OMAP_MUX is not selected omap4: board-omap4panda: Initialise the serial pads omap3: board-3430sdp: Initialise the serial pads omap4: board-4430sdp: Initialise the serial pads omap2+: mux: Add macro for configuring static with omap_hwmod_mux_init omap2+: mux: Remove the use of IDLE flag omap2+: Add separate list for dynamic pads to mux perf: add OMAP support for the new power events OMAP4: Add IVA OPP enteries. OMAP4: Update Voltage Rail Values for MPU, IVA and CORE OMAP4: Enable 800 MHz and 1 GHz MPU-OPP OMAP3+: OPP: Replace voltage values with Macros OMAP3: wdtimer: Fix CORE idle transition Watchdog: omap_wdt: add fine grain runtime-pm ... Fix up various conflicts in - arch/arm/mach-omap2/board-omap3evm.c - arch/arm/mach-omap2/clock3xxx_data.c - arch/arm/mach-omap2/usb-musb.c - arch/arm/plat-omap/include/plat/usb.h - drivers/usb/musb/musb_core.h
