Merge tag 'omap-for-v4.13/soc-v4-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc

SoC changes for omap variants for v4.13 merge window:

- PM clean-up in preparation of adding am335x/am437x PM support

- Fixes for issues found by Coccinelle

- Legacy code removal now that everything boots in device
  tree only mode

- Interconnect changes in preparation of moving clkctrl clocks
  to be managed by clkctrl clock driver

- Interconnect changes to add omap4 crypto acceclerator
  support
