Merge tag 'omap-for-v4.17/soc-pt2-signed' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc

Pull "Two omap5 specific aux control module patches for v4.17" from Tony Lindgren:

On omap5 there is an aux control module that we are not handling
currently for clocks, so let's add support for it.

* tag 'omap-for-v4.17/soc-pt2-signed' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP5: control: add support for control module wkup pad config
  ARM: omap2+: control: add support for auxiliary control module instances
