Message

Hi,

This series adds support for tracking Arm SCMI statistics [Patch 2/3]
A config option to enable this [Patch 2]
Cleans up a unneeded call to handle_scmi_info [Patch 1]
And in [Patch 4] a selection of new debugfs entries to present these statistics

Based on v6.9, Tested on Arm Juno [1]

Thanks,
Luke

V1->V2
Add a minor fix removing an unneeded call to handle_to_scmi_info
Use new scmi_log_stats op/no-op rather than if(IS_ENABLED)
Drop unneeded atomic_set's
Use a helper function for stats debugfs creation
