That sounds good to me, just one comment. Before getting these into
staging, I'd like to have omap variants use proper interconnect
target module in devicetree like we already have in omap4.dtsi
as target-module@56000000. This should simplify things further
as the module child device driver(s) can just enable things with
runtime PM and we can leave out all the legacy hwmod platform data
that sounds like you're still carrying.

I have patches here to add similar interconnect target modules for
at least omap34xx, omap36xx, omap5, and am335x that I'll try to post
later on today to play with. For am335x, things still depend on the
recentely posted prm rstctrl patches. I'm not sure if I already
did a dts patch for dra7 yet, need to check.

Tony
