X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=753355d6200753f4d8cb8db794339ad46d471d7d;p=thirdparty%2Flinux.git Merge tag 'scmi-updates-6.17' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI updates for v6.17 1. A fix is introduced to correct turbo frequency marking for 64-bit devices with sustained frequencies over 4GHz, ensuring accurate turbo frequency identification. 2. Debug capabilities are being improved by introducing in-flight transfer tracking using debug counters, which help diagnose transfer congestion and behavior. Additional tracepoints are added to log in-flight counts at transfer begin and end, offering better runtime insight. The debug counters now support decrement operations using a newly added scmi_dec_count helper, making counter tracking symmetric and more robust. 3. A race condition in suspend-resume logic is being resolved by ensuring SCMI_SYSPOWER_IDLE state is set early during resume, improving suspend reliability under certain conditions. New suspend and resume operations are added to the scmi_bus_type to enable finer power management control for SCMI-based devices. 4. Finally enhancements are also made to avoid registering notifiers for events that a platform does not support, reducing unnecessary overhead by checking for unsupported event types during protocolinitialization. * tag 'scmi-updates-6.17' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_scmi: Convert to SYSTEM_SLEEP_PM_OPS firmware: arm_scmi: Avoid notifier registration for unsupported events firmware: arm_scmi: power_control: Ensure SCMI_SYSPOWER_IDLE is set early during resume firmware: arm_scmi: Add power management operations to SCMI bus include: trace: Add tracepoint support for inflight xfer count firmware: arm_scmi: Track number of inflight SCMI transfers firmware: arm_scmi: Add support for debug counter decrement firmware: arm_scmi: Fix up turbo frequencies selection Link: https://lore.kernel.org/r/20250709122907.1171913-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann --- 753355d6200753f4d8cb8db794339ad46d471d7d
