Merge tag 'omap-fixes-a-for-3.10-rc' of git://git.kernel.org/pub/scm/linux/kernel...

From Paul Walmsley:
Fix the OMAP serial driver to work correctly on OMAP4 when booting
with DT.

* tag 'omap-fixes-a-for-3.10-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending:
  ARM: OMAP2+: hwmod: Remove sysc slave idle and auto idle apis
  SERIAL: OMAP: Remove the slave idle handling from the driver
  ARM: OMAP2+: serial: Remove the un-used slave idle hooks
  ARM: OMAP2+: hwmod-data: UART IP needs software control to manage sidle modes
  ARM: OMAP2+: hwmod: Add a new flag to handle SIDLE in SWSUP only in active
  ARM: OMAP2+: hwmod: Fix sidle programming in _enable_sysc()/_idle_sysc()
