[Sudeep Holla]

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.

  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.
