* 'omap-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6: (243 commits) omap2: Make OMAP2PLUS select OMAP_DM_TIMER OMAP4: hwmod data: Fix alignment and end of line in structurefields OMAP4: hwmod data: Move the DMA structures OMAP4: hwmod data: Move the smartreflex structures OMAP4: hwmod data: Fix missing SIDLE_SMART_WKUP in smartreflexsysc arm: omap: tusb6010: add name for MUSB IRQ arm: omap: craneboard: Add USB EHCI support omap2+: Initialize serial port for dynamic remuxing for n8x0 omap2+: Add struct omap_board_data and use it for platform level serial init omap2+: Allow hwmod state changes to mux pads based on the state changes omap2+: Add support for hwmod specific muxing of devices omap2+: Add omap_mux_get_by_name OMAP2: PM: fix compile error when !CONFIG_SUSPEND MAINTAINERS: OMAP: hwmod: update hwmod code, data maintainership OMAP4: Smartreflex framework extensions OMAP4: hwmod: Add inital data for smartreflex modules. OMAP4: PM: Program correct init voltages for scalable VDDs OMAP4: Adding voltage driver support OMAP4: Register voltage PMIC parameters with the voltage layer OMAP3: PM: Program correct init voltages for VDD1 and VDD2 ...
