Pull Char/Misc/IIO/Binder updates from Greg KH:
"Here is the big set of char/misc/iio and other driver subsystem
changes for 6.18-rc1.
Loads of different stuff in here, it was a busy development cycle in
lots of different subsystems, with over 27k new lines added to the
tree.
Included in here are:
- IIO updates including new drivers, reworking of existing apis, and
other goodness in the sensor subsystems
- MEI driver updates and additions
- NVMEM driver updates
- slimbus removal for an unused driver and some other minor updates
- coresight driver updates and additions
- MHI driver updates
- comedi driver updates and fixes
- extcon driver updates
- interconnect driver additions
- eeprom driver updates and fixes
- minor UIO driver updates
- tiny W1 driver updates
But the majority of new code is in the rust bindings and additions,
which includes:
- misc driver rust binding updates for read/write support, we can now
write "normal" misc drivers in rust fully, and the sample driver
shows how this can be done.
- Initial framework for USB driver rust bindings, which are disabled
for now in the build, due to limited support, but coming in through
this tree due to dependencies on other rust binding changes that
were in here. I'll be enabling these back on in the build in the
usb.git tree after -rc1 is out so that developers can continue to
work on these in linux-next over the next development cycle.
- Android Binder driver implemented in Rust.
This is the big one, and was driving a huge majority of the rust
binding work over the past years. Right now there are two binder
drivers in the kernel, selected only at build time as to which one
to use as binder wants to be included in the system at boot time.
The binder C maintainers all agreed on this, as eventually, they
want the C code to be removed from the tree, but it will take a few
releases to get there while both are maintained to ensure that the
rust implementation is fully stable and compliant with the existing
userspace apis.
All of these have been in linux-next for a while"
