This is a new iteration on the Mobileye system-controller series [0].
It has been split into separate series to facilitate 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 [1], pinctrl [2] and MIPS [3].

Have a nice day,
Théo

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.
