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"

Pull SoC devicetree updates from Arnd Bergmann:
"We see the addition of eleven new SoCs, including a total of sixx
arm64 chips from Qualcomm alone. Overall, the Qualcomm platforms once
again make up the majority of all changes, after a couple of quieter
releases.
The new SoCs in this branch are:
- Microchip sama7d65 is a new 32-bit embedded chip with a single
Cortex-A7 and the current high end of the old Atmel SoC line.
- Samsung Exynos 9810 is a mobile phone chip used in some older
phones like the Samsung Galaxy S9
- Renesas R-Car V4H ES3.0 (R8A779G3) is an updated version of the V4H
(R8A779G0) low-power automotive SoC
- Renesas RZ/G3E (R0A09G047) is a family of embedded chips using
Cortex-A55 cores
- Qualcomm Snapdragon 8 Elite (SM8750) is a new phone chip based on
Qualcomm's Oryon CPU cores.
- Qualcomm Snapdragon AR2 (SAR2130P) is a SoC for augmented reality
glasses.
- Qualcomm IQ6 (QCS610) and IQ8 (QCS8300) are two industrial IOT
platforms.
- Snapdragon 425 (MSM8917) is a mobile phone SoC from 2016
- Qualcomm IPQ5424 is a Wi-Fi 7 networking chip
All of the above are part of already supported SoC families that only
need new devicetree files. Two additional SoCs in new families are
part of a separate branch.
There are 48 new machines in total, including six arm32 ones based on
aspeed. broadcom, microchip and st SoCs all using Cortex-A7 cores, and
a single risc-v board, the Banana Pi R3.
The remaining ones use arm64 chips from Broadcom, Samsung, NXP,
Mediatek, Qualcomm, Renesas and Rockchips and cover development
boards, phones, laptops, industrial machines routers.
A lot of ongoing work is for cleaning up build time warnings and other
issues, in addition to the new machines and added features"

Add bindings for the MediaTek External Memory Interface Interconnect,
which providers support system bandwidth requirements through Dynamic
Voltage Frequency Scaling Resource Collector (DVFSRC) hardware.
This adds bindings for MediaTek MT8183 and MT8195 SoCs.
Note that this is modeled as a subnode of DVFSRC for multiple reasons:
- Some SoCs have more than one interconnect on the DVFSRC (and two
different kinds of EMI interconnect, and also a SMI interconnect);
- Some boards will want to not enable the interconnect driver because
some of those are not battery powered (so they just keep the knobs
at full thrust from the bootloader and never care scaling busses);
- Some DVFSRC interconnect features may depend on firmware.

The downstream kernel has infrastructure for passing votes from different
interconnect nodes onto different RPMh RSCs. This neither implemented, not
is going to be implemented upstream (in favor of a different solution
using ICC tags through the same node).
Unfortunately, as it happens, meaningless (in the upstream context) parts
of the vendor driver were copied, ending up causing havoc - since all
"per-RSC" (in quotes because they all point to the main APPS one) BCMs
defined within the driver overwrite the value in RPMh on every
aggregation.
To both avoid keeping bogus code around and possibly introducing
impossible-to-track-down bugs (busses shutting down for no reason), get
rid of the duplicated ICC node definitions.

SM8250 (like SM8150 but unlike all other QUP-equipped SoCs) doesn't
provide a qup-core path. Adjust the bindings and drivers as necessary,
and then describe the icc paths in the device tree. This makes it possible
for interconnect sync_state succeed so long as you don't use UFS.

This patchset is to support i.MX8MP NoC settings, i.MX8MP NoC initial
value after power up is invalid, need set a valid value after related
power domain up.
This patchset also includes two patch[1,2] during my development to enable
the ICC feature for i.MX8MP.
I not include ddrc DVFS in this patchset, ths patchset is only to
support NoC value mode/priority/ext_control being set to a valid value
that suggested by i.MX Chip Design Team. The value is same as NXP
downstream one inside Arm Trusted Firmware:
