Subject: [PATCH v3 0/1] Add ARM SCMI Powercap driver
Date: Thu, 13 Oct 2022 18:46:11 +0100 [thread overview]
Message-ID: <20221013174612.393830-1-cristian.marussi@arm.com> (raw)
Hi all,
this patch 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 have been squashed into this
patch in V3.
Based on v6.0.
Thanks,
Cristian
