Merge tag 'omap-cleanup-for-v3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup

From Tony Lindgren <tony@atomide.com>

Here is some more omap clean-up. The biggest changes are
hwmod, clock, and System Control Module cleanup, and the removal
of the last instance of omap_read/write usage for omap2+ with
the removal of unused USB OHCI Full Speed driver support. The
removed OHCI is only currently used for omap1 as the actively
used omap2+ boards have either MUSB or another instance of
OHCI+EHCI that's more usable.

* tag 'omap-cleanup-for-v3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP2+: hwmod: remove prm_clkdm, cm_clkdm; allow hwmods to have no clockdomain
  ARM: OMAP3: Move McBSP fck clock alias to hwmod data
  ARM: OMAP2: Move McBSP fck clock alias to hwmod data for OMAP2430
  ARM: OMAP2: Move McBSP fck clock alias to hwmod data for OMAP2420
  ARM: OMAP: dsp: interface to control module functions
  ARM: OMAP2+: control: new APIs to configure boot address and mode
  ARM: OMAP2+: CLEANUP: Remove ARCH_OMAPx ifdef from struct dpll_data
  ARM: OMAP2+: hwmod: use init-time function pointer for _init_clkdm
  ARM: OMAP2+: hwmod: use init-time function pointer for hardreset
  ARM: OMAP2+: hwmod: use init-time function pointer for wait_target_ready
  ARM: OMAP4: hwmod: drop extra cpu_is check from _wait_target_disable()
  ARM: OMAP2+: hwmod: use init-time function ptrs for enable/disable module
  ARM: OMAP4: hwmod: rename _enable_module to _omap4_enable_module()
  ARM: OMAP: Make FS USB omap1 only
  ARM: OMAP2: Remove legacy USB FS support
  ARM: OMAP3: There is no FS USB controller on omap3
  ARM: OMAP: dma: Clear status registers on enable/disable irq
