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.
