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 ...
