[PATCH v3 0/5] Add support for the PolarFire SoC system controller

[conor.dooley at microchip.com]

From: Conor Dooley <conor.dooley at microchip.com>

This patch series adds support for the system controller on
the PolarFire SoC, using the mailbox framework. A Microchip directory
in the SoC subsystem has been created to hold the mailbox client
driver and will be used for future service drivers.

This directory is included by the kconfig option:
CONFIG_SOC_MICROCHIP_POLARFIRE, so this patch series depends on Atish
Patra's PolarFire SoC support patches which introduce that option.

It further depends on the MAINTAINERS entry created in the same series.

Changes from v2:
* Further reworked dt bindings to satisfy errors and feedback
  (hopefully phandle array is the correct type for the mboxes)
* Full maintainers entry moved to Atish's PFSoC support series, this series now only adds mailbox driver
* Converted config options from MPFS to POLARFIRE_SOC so they are more recognisable
* Further simplified driver code from feedback

Changes from v1:
* Squashed header into first patch
* Fixed DT binding warnings & small fixes
* Cleaned up drivers from feedback
