I only got a "applied" reply from Marks scripts for patch 3/5, so only today
saw that all 3 actually got applied.

Anyway, I've applied this to my dts32-branch for 4.8 now [0] with some
modifications regarding
- the commit subject+message
- ordering
- io_domains access (via the phandle now)
- regulator suspend property
so maybe take a look and holler if you see a mistake.

I was able to get audio over the headphones (so definitly an improvement),
but so far not over the built-in speakers. Did you need to do something
special in the configuration for this?
