Hi all,
this short series builts on top of recently introduced SCMI v3.1 Powercap protocol to implement an ARM SCMI Powercap driver which takes care to expose via the Powercap framework all the SCMI Powercap zones that have been discovered asking the SCMI platform firmware.
Basic testing has been performed against an emulated SCMI platform supporting SCMIv3.1 Powercap protocol using powercap-utils.
A couple of fixes spotted with Smatch by Dan are queued on top of the driver itself; these may have to be squashed finally into the driver itself but for now I have just added them here as patches on top, for clarity and to preserve authorship.
The series is based on sudeep/for-next/scmi [1] on top of
commit 40d30cf680cb ("firmware: arm_scmi: Harmonize SCMI tracing message format")
Thanks, Cristian --- v1 --> v2 - using clamp_t() to simplify normalizations - cleanup style in block of var declarations - refactor scale conversions code - add MAINTAINER entry - refactored normalizations and added dev_dbg
