Merge tag 'omap-fixes-for-v3.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

The biggest fix here is the long pending patch mux UART pins so PM
retention idle works again.

Also included are few other PM wake-up related fixes, and removal of
dead cpu detection code.

The other fixes are trivial build and randconfig related fixes.

* tag 'omap-fixes-for-v3.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP2+: Fix compile for CONFIG_TIDSPBRIDGE platform init code
  ARM: OMAP3: Fix omap3_l3_block_irq warning when CONFIG_BUG is not set
  ARM: OMAP: Fix MMC_OMAP build when only MMC_OMAP_HS is selected
  OMAP2+: UART: Add mechanism to probe uart pins and configure rx wakeup
  ARM: OMAP: Fix lis3lv02d accelerometer to use gpio_to_irq
  ARM: OMAP: SoC detection: remove unused cpu_is macros
  ARM: OMAP3: clock data: cleanup AM3[35]x SoC detection
  arm: omap3: am35x: Don't mark missing features as present
  ARM: OMAP3: PM: fix shared PRCM interrupts: leave disabled at boot
  ARM: OMAP2+: INTC: fix suspend abort, set IRQCHIP_SKIP_SET_WAKE
