Merge branch 'omap-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6 

* 'omap-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6: (26 commits)
  OMAP2 clock: dynamically allocate CPUFreq frequency table
  OMAP clock/CPUFreq: add clk_exit_cpufreq_table()
  OMAP2xxx OPP: clean up comments in OPP data
  OMAP2xxx clock: clk2xxx.c doesn't compile if CPUFREQ is enabled
  OMAP1 clock: remove __initdata from struct clk_functions to prevent crash
  OMAP1 clock: Add missing clocks for OMAP 7xx
  OMAP clock: remove incorrect EXPORT_SYMBOL()s
  OMAP3 clock: Add capability to change rate of dpll4_m5_ck
  OMAP3 clock: McBSP 2, 3, 4 functional clock parent is PER_96M_FCLK, not CORE_96M_FCLK
  OMAP3: clock: add clockdomains for UART1 & 2
  OMAP2420 IO mapping: move IVA mapping virtual address out of vmalloc space
  OMAP2xxx IO mapping: mark DSP mappings as being 2420-only
  ARM: OMAP3: PM: Fix the Invalid CM_CLKSTCTRL reg access.
  OMAP2: remove duplicated #include
  omap3: EVM: Choose OMAP_PACKAGE_CBB
  omap3: Fix booting if package is uninitialized
  omap3: add missing parentheses
  omap3: add missing parentheses
  omap2/3: ZOOM: Correcting key mapping for few keys
  omap2/3: make serial_in_override() address the right uart port
