Hi ARM SoC Team,
Please pull !
Sorry for the delayed pull request, was waiting for Ack from clk
maintainers for some trivial changes but Stephen had some comments/
discussion on one of them, so dropped all clk changes due to dependencies.
All the other changes are in -next for a while now.
Regards,
Sudeep

MAINTAINERS: Update SCMI entry with HWMON driver (2024-02-23 02:01:13 +0000)
----------------------------------------------------------------
Arm SCMI updates for v6.9
Quite a few changes to extend support to SCMI v3.2 specification,
to enhance notification handling and other miscellaneous updates.
1. Enhancements to notification handling
Until now, trying to register a notifier for an unsuppported
notification returned an error genrating unneeded message exchanges
with the SCMI platform. This can be avoided by looking up in advance
the specific protocol and resources available.
With these changes SCMI driver user will fail to register a notifier
if the related command or resource is not supported (like before)
without the need of exchanging any message.
Perf notifications are also extended to provide the pre-calculated
frequencies corresponding to the level or index carried by the
2. More SCMI v3.2 related updates
One of the main addition includes a centralized support to the SCMI
core to handle v3.2 optional protocol version negotiation, so that
at protocol initialization time, if the platform advertised version
is newer than supported by the kernel and protocol version negotiation
is supported, the SCMI core will attempt to negotiate an older protocol
version.
It also includes the clock get permissions which indicates if any of
the clock operations are forbidden by the platform for the OSPM agent.
It can be used in the clock driver to avoid unnecessary message
exchanges between the kernel and the platform which will always end
up with the failure. It also includes other missing bits of clock
v3.2 protocol so that the supported protocol version can be bumped
to 0x30000 (v3.2).
3. Miscellaneous updates
This includes addition of warning if the domain frequency multiplier
is 0 or rounded off to indicate the actual frequencies are either
wrong ot rounded off, hardening of clock domain info lookups, addition
of multiple protocols registration support within a SCMI driver,
update to SCMI entry in MAINTAINERS to include HWMON driver and
constifying the scmi_bus_type structure.
This also includes couple for fixes to minor issues: double free in
SMC transport cleanup path and struct kernel-doc warnings in optee
transport.
