<div class='commit-subject'>Merge tag 'omap-for-v4.7/fixes-powedomain' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes</div><div class='commit-msg'>Fixes for omaps for v4.7-rc cycle:

- Fix dra7 for hardware issues limiting L4Per and L3init power domains
  to on state. Without this the devices may not work correctly after
  some time of use because of asymmetric aging. And related to this,
  let's also remove the unusable states.

- Always select omap interconnect for am43x as otherwise the am43x
  only configurations will not boot properly. This can happen easily
  for any product kernels that leave out other SoCs to save memory.

- Fix DSS PLL2 addresses that have gone unused for now

- Select erratum 430973 for omap3, this is now safe to do and can
  save quite a bit of debugging time for people who may have left
  it out.
