Pull "ARM SCMI support for v4.17" from Sudeep Holla:

ARM System Control and Management Interface(SCMI)[1] is more flexible and
easily extensible than any of the existing interfaces.

Few existing as well as future ARM platforms provide micro-controllers
to abstract various power and other system management tasks which have
similar interfaces, both in terms of the functions that are provided by
them, and in terms of how requests are communicated to them.

There are quite a few protocols like ARM SCPI, TI SCI, QCOM RPM, Nvidia Tegra
BPMP, and so on already. This specification is to standardize and avoid any
further fragmentation in the design of such interface by various vendors.

The current SCMI driver implementation is very basic and initial support.
It lacks support for notifications, asynchronous/delayed response, perf/power
statistics region and sensor register region.

Mailbox is the only form of transport supported currently in the driver.
SCMI supports interrupt based mailbox communication, where, on completion
of the processing of a message, the caller receives an interrupt as well as
polling for completion.

SCMI is designed to minimize the dependency on the mailbox/transport
hardware. So in terms of SCMI, each channel in the mailbox includes
memory area, doorbell and completion interrupt.

However the doorbell and completion interrupt is highly mailbox dependent
which was bit of controversial as part of SCMI/mailbox discussions.

Arnd and me discussed about the few aspects of SCMI and the mailbox framework:

1. Use of mailbox framework for doorbell type mailbox controller:
   - Such hardware may not require any data to be sent to signal the remote
     about the presence of a message. The channel will have in-built
     information on how to trigger the signal to the remote.
     There are few mailbox controller drivers which are purely doorbell based.
     e.g.QCOM IPC, STM, Tegra, ACPI PCC,..etc

2. Supporting other mailbox controller:
   - SCMI just needs a mechanism to signal the remote firmware. Such
     controller may need fixed message to be sent to trigger a doorbell.
     In such case we may need to get that data from DT and pass the same
     to the controller. It's not covered in the current DT binding, but
     can be extended as optional property in future.

     However handling notifications may be interesting on such mailbox, but
     again there is no way to interpret what the data field(remote message)
     means, it could be a bit mask or a number or don't-care.

Arnd mentioned that he doesn't like the way the mailbox binding deals
with doorbell-type hardware, but we do have quite a few precedent drivers
already and changing the binding to add a data field would not make it any
better, but could cause other problems. So he is happy with the status quo
of SCMI implementation.

Depending directly on the bus driver's global cci_ctrl_base variable
is a little unpleasant, and exporting it to allow the PMU driver to
be modular would be even more so. Let's make things a little better
abstracted by adding the control register block to the cci_pmu instance
data alongside the PMU register block, and communicating the mapped
address from the bus driver via platform data.

It's not practical to try the same thing for the bus driver itself,
given that the globals are entangled with the hairy assembly code for
port control, so we leave them be there. It would however be prudent
to move them to the __ro_after_init section in passing, since the
addresses really should never be changing once set.

The arm-cci driver is really two entirely separate drivers; one for MCPM
port control and the other for the performance monitors. Since they are
already relatively self-contained, let's take the plunge and move the
PMU parts out to drivers/perf where they belong these days. For non-MCPM
systems this leaves a small dependency on the remaining "bus" stub for
initial probing and discovery, but we end up with something that still
fits the general pattern of its fellow system PMU drivers to ease future
maintenance.

Moving code to a new file also offers a perfect excuse to modernise the
license/copyright headers and clean up some funky linewraps on the way.
