Hello Greg,

This is the pull request with interconnect updates for the 6.6-rc1 merge
window. In contains a mix of core and driver changes as usual. This time
it might look a bit bigger as lines of code, but 97.5% of these are related
to expanding some macros in drivers and bring no functional change. There
are also a few patches that touch qcom clock drivers and these are in
immutable branch that is pulled also by the qcom tree. It contains also a
debugfs patch that you acked recently. The complete summary and details
are in the signed tag.

All patches have been in linux-next during last few days. Please pull into
char-misc-next when possible.

Thanks,
Georgi

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.
