"Here is the "big" set of char/misc and other driver subsystem changes
for 6.11-rc1. Nothing major in here, just loads of new drivers and
updates. Included in here are:
- IIO api updates and new drivers added
- wait_interruptable_timeout() api cleanups for some drivers
- MODULE_DESCRIPTION() additions for loads of drivers
- parport out-of-bounds fix
- interconnect driver updates and additions
- mhi driver updates and additions
- w1 driver fixes
- binder speedups and fixes
- eeprom driver updates
- coresight driver updates
- counter driver update
- new misc driver additions
- other minor api updates
All of these, EXCEPT for the final Kconfig build fix for 32bit
systems, have been in linux-next for a while with no reported issues.
The Kconfig fixup went in 29 hours ago, so might have missed the
latest linux-next, but was acked by everyone involved"

This series adds QoS support for QNOC type device which can be found on

priority forward disable and urgency forwarding. This helps in

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.

This series adds interconnect support for the Qualcomm X1E80100 platform,
aka Snapdragon X Elite.
Our v1 post of the patchsets adding support for Snapdragon X Elite SoC had
the part number sc8380xp which is now updated to the new part number x1e80100
based on the new branding scheme and refers to the exact same SoC.

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.

"Here is the "big" set of char/misc and other driver subsystems for
6.4-rc1.
It's pretty big, but due to the removal of pcmcia drivers, almost
breaks even for number of lines added vs. removed, a nice change.
Included in here are:
- removal of unused PCMCIA drivers (finally!)
- Interconnect driver updates and additions
- Lots of IIO driver updates and additions
- MHI driver updates
- Coresight driver updates
- NVMEM driver updates, which required some OF updates
- W1 driver updates and a new maintainer to manage the subsystem
- FPGA driver updates
- New driver subsystem, CDX, for AMD systems
- lots of other small driver updates and additions

BWMONv4 has two sets of registers: one for handling the monitor itself
and one called "global" which hosts some sort of a headswitch and an
interrupt control register. We did not handle that one before, as on
SoCs starting with SDM845 they have been merged into a single contiguous
range.
To make the qcom,msm8998-bwmon less confusing and in preparation for
actual MSM8998 support, describe the global register space and introduce
new "qcom,sdm845-cpu-bwmon" compatible while keeping the
"qcom,sdm845-bwmon" as a fallback for SoCs with this merged register space
scheme.
