Subject: [PATCH v4 0/5] Add initial Keem Bay SoC / Board support

Hi,

This patch-set adds initial support for a new Intel Movidius SoC code-named
Keem Bay. The SoC couples an ARM Cortex A53 CPU with an Intel Movidius VPU.

This initial patch-set enables only the minimal set of components required
to make the Keem Bay EVM board boot into initramfs.

Changes from v3 to v4:
* Renamed SoC dt-bindings file to intel,keembay.yaml
* Dropped clock and power domain dt-binding header files (because currently
unused)

Changes from v2 to v3:
* Split dt-bindings patch into 3 different patches (SoC/board bindings,
clock bindings, and power domains bindings).
* Added dual license (GPL-2.0-only or BSD-3-Clause) to dt-bindings header
files and DTS files.

Changes from v1 to v2:
* Moved keembay-scmi-mailbox driver to a separate patchset
* Removed Keem Bay SCMI mailbox and SCMI node from Keem Bay SoC device tree

Regards,
Daniele
