Linus Torvalds 0df0914d41 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
  ...
