Hi,

this series introduces the support for the new SCMI Voltage Domain Protocol
defined by the upcoming SCMIv3.0 specification, whose BETA release is
available at [1].

Afterwards, a new generic SCMI Regulator driver is developed on top of the
new SCMI VD Protocol.

The series is currently based on for-next/scmi [2] on top of:

commit 66d90f6ecee7 ("firmware: arm_scmi: Enable building as a single
	     module")

Any feedback welcome,

Well, this is just great! We were right about to develop a proprietary SCMI
protocol in order to control a locked down PMIC accessible behind a secured
firmware. We would have done essentially just that since the use case is to
control the various regulators exposed by this PMIC over SCMI. Thanks a lot!

You're welcome :D ... any feedback from your independent testing will be
appreciated.

Thanks

Cristian
