Fixes for omaps for v4.4-rc cycle:

- A series of audio changes for dra7 that missed the merge window but turned
   out to be necessary to fix a boot time imprecise external abort error and to
   getaudio working
 
 - Fix l4 related boot time errors for dm81xx
 
 - Use lockless cldm/pwrdm api in omap4_boot_secondary
 
 - Remove t410 custom abort handler that is no longer needed and may
   hide other critical errors
 
 - Mark cpuidle tracepoints as _rcuidle
 
 - Fix module alias for omap-ocp2scp

Merge tag 'omap-for-v4.4/fixes-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

Merge "Fixes for omaps for v4.4-rc cycle" from Tony Lindgren:

- A series of audio changes for dra7 that missed the merge window but turned
  out to be necessary to fix a boot time imprecise external abort error and to
  getaudio working

- Fix l4 related boot time errors for dm81xx

- Use lockless cldm/pwrdm api in omap4_boot_secondary

- Remove t410 custom abort handler that is no longer needed and may
  hide other critical errors

- Mark cpuidle tracepoints as _rcuidle

- Fix module alias for omap-ocp2scp

* tag 'omap-for-v4.4/fixes-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP4+: SMP: use lockless clkdm/pwrdm api in omap4_boot_secondary
  arm: omap2+: add missing HWMOD_NO_IDLEST in 81xx hwmod data
  ARM: OMAP2+: remove custom abort handler for t410
  ARM: OMAP: DRA7: hwmod: Add data for McASP3
  ARM: OMAP2+: hwmod: Add hwmod flag for HWMOD_OPT_CLKS_NEEDED
  ARM: dts: dra7: Fix McASP3 node regarding to clocks
  bus: omap-ocp2scp: Fix module alias
  ARM: OMAP2+: PM: Denote the cpuidle tracepoints as _rcuidle()
