[GIT PULL] Driver core changes for 6.11-rc1
From: Greg KH
Date: Thu Jul 25 2024 - 03:36:44 EST
***************
This merge request is coming late in the -rc1 cycle on purpose. I
wanted to make sure that the merge issues and other problems were all
resoved due to some core api changes (platform and bus structures)
happening in this tree.
You will have merge conflicts with your tree when you pull from here in
the following two files:
drivers/fsi/fsi-occ.c
drivers/reset/reset-meson-audio-arb.c
the resolution for them should be "obvious", and has been in linux-next
for a while now.
You will also get build errors for the following two platform drivers:
drivers/net/ethernet/renesas/rtsn.c
drivers/gpu/drm/stm/lvds.c
due to these new files coming in during the merge window and them not
being in my branch. They too have fixups that have been in linux-next
for a while.
I have all of the above problems resolved in the following branch:
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git driver-core-6.11-rc1-merge-resolution
if you want to compare things, OR you can just pull from that point as
well, I can make a signed tag for you there if that makes it simpler.
Sorry for the conflicts,
greg k-h

Driver core changes for 6.11-rc1
Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases to
get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions. It's not all that useful for a "write a whole driver
in rust" type of thing, but the firmware bindings do help out the
phy rust drivers, and the driver core bindings give a solid base on
which others can start their work. There is still a long way to go
here before we have a multitude of rust drivers being added, but
it's a great first step.
- driver core const api changes. This reached across all bus types,
and there are some fix-ups for some not-common bus types that
linux-next and 0-day testing shook out. This work is being done to
help make the rust bindings more safe, as well as the C code, moving
toward the end-goal of allowing us to put driver structures into
read-only memory. We aren't there yet, but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes
- other minor driver core cleanups
All of these have been in linux-next for a very long time with no
reported problems.
