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.

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
All of these have been in linux-next for a while with no reported

Pull char/misc drivers updates from Greg KH:
"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
All of these have been in linux-next for a while with no reported
issues"

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.

MSM8996 A2NoC contains a UFS master, which means the UFS hardware is
accessed every time sync_state is called within the interconnect
framework. It's all good on devices where this clock is already enabled

rather unlikely to have it like that. Add the missing 2 clocks to the

This patch set is to support bucket in icc-rpm driver, so it implements
the similar mechanism in the icc-rpmh driver.
It uses interconnect path tag to indicate the bandwidth voting is for
which buckets, and there have three kinds of buckets: AWC, WAKE and
SLEEP, finally the wake and sleep bucket values are used to set the
corresponding clock (active and sleep clocks). So far, we keep the AWC
bucket but doesn't really use it.

property is updated as enumerate values: 1 or 2. Setting to 1 means
it is compatible with old DT binding that interconnect path only

Here is the large set of char, misc, and other driver subsystem updates
for 5.19-rc1. The merge request for this has been delayed as I wanted
to get lots of linux-next testing due to some late arrivals of changes
for the habannalabs driver.
Highlights of this merge are:
- habanalabs driver updates for new hardware types and fixes and
other updates
- IIO driver tree merge which includes loads of new IIO drivers
and cleanups and additions
- PHY driver tree merge with new drivers and small updates to
existing ones
- interconnect driver tree merge with fixes and updates
- soundwire driver tree merge with some small fixes
- coresight driver tree merge with small fixes and updates
- mhi bus driver tree merge with lots of updates and new device
support
- firmware driver updates
- fpga driver updates
- lkdtm driver updates (with a merge conflict, more on that
below)
- extcon driver tree merge with small updates
- lots of other tiny driver updates and fixes and cleanups, full
details in the shortlog.
All of these have been in linux-next for almost 2 weeks with no reported
problems.
Note, there are 3 merge conflicts when merging this with your tree:
- MAINTAINERS, should be easy to resolve
- drivers/slimbus/qcom-ctrl.c, should be straightforward
resolution
- drivers/misc/lkdtm/stackleak.c, not an easy resolution. This
has been noted in the linux-next tree for a while, and
resolved there, here's a link to the resolution that Stephen
came up with and that Kees says is correct:
https://lore.kernel.org/r/20220509185344.3fe1a354@canb.auug.org.au
I will be glad to provide a merge point that contains these resolutions
if that makes things any easier for you.
