Subject: [GIT PULL] i2c-host for v6.15
Hi Wolfram,
Here we go with the pull request for the merge window.
It's not a huge batch in terms of patch count, but a few pieces
of long standing work finally reached the finish line.
Some patches are refreshed from the past, something I plan to do
more often going forward.
One new driver was added: Spacemit K1.
Andy has also been very active, contributing the new
i2c_10bit_addr_*_from_msg() helper, which is now being adopted
across several drivers.
I don't think I've missed anything from the recent submissions,
and I'm happy to have caught up with the pending work. So I
don't expect the need for a part 2 pull request next week.
Thanks, and I wish you a great weekend!
Andi
