Message-ID: <20230612121017.4108104-1-sudeep.holla@arm.com> (raw)
Hi ARM SoC Team,
Please pull ! The powercap driver related changes that have dependency
on the firmware driver part are acked-by Rafael and agreed to merge the
changes via SoC tree. All the changes are in -next for a while now.
Regards,

powercap: arm_scmi: Add support for disabling powercaps on a zone (2023-06-06 14:05:10 +0100)
----------------------------------------------------------------
Arm SCMI updates for v6.5
Couple of main additions :-
1. Support for multiple SMC/HVC transports for SCMI:
Some platforms need to support multiple SCMI instances within
a platform(more commonly in a VM). The same SMC/HVC FID is used with
all the instances. The platform or the hypervisor needs a way to
distinguish among SMC/HVC calls made from different instances.
This change adds support for passing shmem channel address as the
parameters in the SMC/HVC call. The address is split into 4KB-page
and offset for simiplicity.
2. Addition od SCMI v3.2 explicit powercap enable/disable support:
SCMI v3.2 specification introduces support to disable powercapping
as a whole on the desired zones.
This change adds the needed support to the core SCMI powercap protocol,
exposing enable/disable protocol operations and then wiring up the new
operartions in the related powercap framework helpers.
