Hi Wolfram, Dmitry,

here's the full set of patches that I've been running local tests on and
which looks like it has no other issues. I'm going to run this through
our internal test system to make sure there aren't any regressions. I
can carry these in the Tegra tree for a little bit until we're
reasonable sure that these patches are all safe to apply and then send a
pull request sometime next week.

I've also included a patch as suggested by Dmitry to keep I2C interrupts
enabled during suspend/resume and I'm currently checking if that may be
a fix for a suspend/resume issue that I've seen on Jetson Nano where we
don't have working suspend/resume yet.
