This is a new iteration on the Mobileye system-controller series. It
used to be sent as a single series [0], but has been split in the
previous revision (see [1], [2], [3], [4]) to faciliate merging.

This series adds a platform driver dealing with read-only PLLs derived
from the main crystal, and some divider clocks based on those PLLs. It
also acts at the one instantiating reset and pinctrl auxiliary devices.

One special feature is that some clocks are required before platform
bus infrastructure is available; we therefore register some clocks at
the of_clk_init() stage.

We support EyeQ5, EyeQ6L and EyeQ6H SoCs. The last one is special in
that there are seven instances of this system-controller. All of those
handle clocks.

Related series are targeted at reset [5], pinctrl [6] and MIPS [4]. The
first two are receiving a second version. The last one has no change
and stays at its V1.

Have a nice day,
Théo

Changes in v2:
- bindings: take Acked-by: Krzysztof Kozlowski.
- driver: eqc_auxdev_create(): cast the `void __iomem *base` variable to
  (void __force *) before putting it in platform_data, to avoid sparse
  warning.
- Link to v1: see [1]

Changes since OLB v3 [0]:
 - MAINTAINERS: Move changes into a separate commit to avoid merge
   conflicts. This commit is in the MIPS series [3].
 - dt-bindings: split include/dt-bindings/ changes into its own commit.
   It is part of this clk series.
 - dt-bindings: Take Reviewed-by: Rob Herring. The include/dt-bindings/
   new commit has NOT inherited from it, just to make sure.
