Merge tag 'omap-for-v4.8/soc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc
SoC related changes for omaps for v4.8 merge window:
- A series of DSS platform_data fixes to prepare for DSS driver changes
- Add tblck clck aliases for PWM
- A series of trivial spelling corrections
- Remove bogus eQEP, ePWM and eCAP hwmod entries
- A series of McBSP sidetone fixes
- Remove QSPI and DSS addresses from hwmod, these come from dts
- Fix RSTST register offset for pruss
- Make ti81xx_rtc_hwmod static
- Remove wrongly defined RSTST offset for PER Domain, note
that the subject for this one wrongly has "dts" in the
subject
- Add support for omap5 and dra7 workaround for 801819
- A series of patches to make kexec work for SMP omaps
