From Paul Walmsley:

OMAP clock, powerdomain, clockdomain, and hwmod fixes intended for the
early v3.4-rc series.  Also contains an HSMMC integration refinement
of an earlier hardware bug workaround.

* tag 'omap-fixes-a2-for-3.4rc' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending:
  ARM: OMAP2+: hwmod: Fix wrong SYSC_TYPE1_XXX_MASK bit definitions
  ARM: OMAP2+: hwmod: Make omap_hwmod_softreset wait for reset status
  ARM: OMAP2+: hwmod: Restore sysc after a reset
  ARM: OMAP2+: omap_hwmod: Allow io_ring wakeup configuration for all modules
  ARM: OMAP3: clock data: fill in some missing clockdomains
  ARM: OMAP4: clock data: Force a DPLL clkdm/pwrdm ON before a relock
  ARM: OMAP4: clock data: fix mult and div mask for USB_DPLL
  ARM: OMAP2+: powerdomain: Wait for powerdomain transition in pwrdm_state_switch()
  ARM: OMAP AM3517/3505: clock data: change EMAC clocks aliases
  ARM: OMAP: clock: fix race in disable all clocks
  ARM: OMAP4: hwmod data: Add aliases for McBSP fclk clocks
  ARM: OMAP3xxx: clock data: fix DPLL4 CLKSEL masks
  ARM: OMAP3xxx: HSMMC: avoid erratum workaround when transceiver is attached
  ARM: OMAP44xx: clockdomain data: correct the emu_sys_clkdm CLKTRCTRL data
