Pull char/misc driver updates from Greg KH:
"Here is the big set of char/misc and other small driver subsystem
changes for 6.6-rc1.

Stuff all over the place here, lots of driver updates and changes and
new additions. Short summary is:

- new IIO drivers and updates

- Interconnect driver updates

- fpga driver updates and additions

- fsi driver updates

- mei driver updates

- coresight driver updates

- nvmem driver updates

- counter driver updates

- lots of smaller misc and char driver updates and additions

All of these have been in linux-next for a long time with no reported
problems"

interconnect changes for 6.6

This pull request contains the interconnect changes for the 6.6-rc1 merge
window which is a mix of core and driver changes with the following highlights:

Core changes:
- New generic test client driver that allows issuing bandwidth requests
between endpoints via debugfs.
- Annotate all structs with flexible array members with the __counted_by
attribute.
- Introduce new icc_bw_lock for cases where we need to serialize bandwidth
aggregation and update to decouple that from paths that require memory
allocation.

Driver changes:
- Move the Qualcomm SMD RPM bus-clocks from CCF to interconnect framework
where they actually belong. This brings power management improvements
and reduces the overhead and layering. These changes are in immutable
branch that is being pulled also into the qcom tree.
- Fixes for QUP nodes on SM8250.
- Enable sync_state and keepalive for QCM2290.
- Enable sync_state for SM8450.
- Improve enable_mask-based BCMs handling and fix some bugs.
- Add compatible string for the OSM-L3 on SDM670.
- Add compatible strings for SC7180, SM8250 and SM6350 bandwidth monitors.
- Expand and retire the DEFINE_QNODE and DEFINE_QBCM macros, which have
become ugly beasts with many different arguments.

interconnect: Add debugfs test client

It's often useful during test, debug, and development to issue path

Example usage:
cd /sys/kernel/debug/interconnect/test-client/

# Configure node endpoints for the path from CPU to DDR on
# qcom/sm8550.
echo chm_apps > src_node
echo ebi > dst_node

# Get path between src_node and dst_node. This is only
# necessary after updating the node endpoints.
echo 1 > get

# Set desired BW to 1GBps avg and 2GBps peak.
echo 1000000 > avg_bw
echo 2000000 > peak_bw

# Vote for avg_bw and peak_bw on the latest path from "get".
# Voting for multiple paths is possible by repeating this
# process for different nodes endpoints.

Allowing userspace to directly enable and set bus rates can be dangerous
So, following in the footsteps of the regmap [0] and clk [1] frameworks,
keep these userspace controls compile-time disabled without Kconfig
options to enable them. Enabling this will require code changes to
define INTERCONNECT_ALLOW_WRITE_DEBUGFS.

[1] commit 37215da5553e ("clk: Add support for setting clk_rate via debugfs")
