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: (163 commits) omap: complete removal of machine_desc.io_pg_offst and .phys_io omap: UART: fix wakeup registers for OMAP24xx UART2 omap: Fix spotty MMC voltages ASoC: OMAP4: MCPDM: Remove unnecessary include of plat/control.h serial: omap-serial: fix signess error OMAP3: DMA: Errata i541: sDMA FIFO draining does not finish omap: dma: Fix buffering disable bit setting for omap24xx omap: serial: Fix the boot-up crash/reboot without CONFIG_PM OMAP3: PM: fix scratchpad memory accesses for off-mode omap4: pandaboard: enable the ehci port on pandaboard omap4: pandaboard: Fix the init if CONFIG_MMC_OMAP_HS is not set omap4: pandaboard: remove unused hsmmc definition OMAP: McBSP: Remove null omap44xx ops comment OMAP: McBSP: Swap CLKS source definition OMAP: McBSP: Fix CLKR and FSR signal muxing OMAP2+: clock: reduce the amount of standard debugging while disabling unused clocks OMAP: control: move plat-omap/control.h to mach-omap2/control.h OMAP: split plat-omap/common.c OMAP: McBSP: implement functional clock switching via clock framework OMAP: McBSP: implement McBSP CLKR and FSR signal muxing via mach-omap2/mcbsp.c ... Fixed up trivial conflicts in arch/arm/mach-omap2/ {board-zoom-peripherals.c,devices.c} as per Tony
