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 -->8 The following changes since commit 6bd1b3fede83d8ba5314886062a9bfdada5102a9: firmware: arm_scmi: Fix the clock protocol supported version (2024-01-22 10:01:17 +0000) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux.git tags/scmi-updates-6.9 for you to fetch changes up to c2f0961a45c4a973437285871540c155bed18ccb: 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. ---------------------------------------------------------------- Andre Przywara (1): firmware: arm_scmi: Fix double free in SMC transport cleanup path Cristian Marussi (17): firmware: arm_scmi: Rework clock domain info lookups firmware: arm_scmi: Add multiple protocols registration support firmware: arm_scmi: Check for notification support firmware: arm_scmi: Add a common helper to check if a message is supported firmware: arm_scmi: Implement is_notify_supported callback in perf protocol firmware: arm_scmi: Implement is_notify_supported callback in power protocol firmware: arm_scmi: Implement is_notify_supported callback in system power protocol firmware: arm_scmi: Implement is_notify_supported callback in clock protocol firmware: arm_scmi: Implement is_notify_supported callback in sensor protocol firmware: arm_scmi: Implement is_notify_supported callback in reset protocol firmware: arm_scmi: Implement is_notify_supported callback in powercap protocol firmware: arm_scmi: Use opps_by_lvl to store opps firmware: arm_scmi: Report frequencies in the perf notifications firmware: arm_scmi: Add support for v3.2 NEGOTIATE_PROTOCOL_VERSION firmware: arm_scmi: Add clock check for extended config support firmware: arm_scmi: Add standard clock OEM definitions firmware: arm_scmi: Update the supported clock protocol version Florian Fainelli (1): MAINTAINERS: Update SCMI entry with HWMON driver Peng Fan (1): firmware: arm_scmi: Implement clock get permissions Randy Dunlap (1): firmware: arm_scmi: Fix struct kernel-doc warnings in optee transport Ricardo B.
