This branch contains a cross-section of drivers, including those who are
normally sent to other maintainers/subsystems. I don't see dependencies that
make them a requirement/easier to merge through the SoC tree at this time --
for example the ucc_uart driver updates are mostly independent cleanups.

Am I missing some aspect here, or should those just be merged through
drivers/tty as other driver changes there? At the very least, we expect drivers
that aren't merged through the normal path to have acks from those maintainers.

Mind following up on that? Thanks!

Hi Olof,

Some of the driver cleanups are dependent to core QE changes.  Some
maybe not but could have contextual dependency with other patches.  I
will be easier to have them all go in from the same place.  We have
collected the ack and confirmation from all the related maintainers.
For the ucc_uart it is not a formal ack.  Quoted the confirmation from
Greg below:

That's fine, all are now dropped from my tree.  Li Yang, feel free to
take them in your tree if you want to.

Ok, getting that in the pull request (tag) would be useful for future cases.

Merging. Thanks!
