[PATCH 0/5] Add support for Mobileye EyeQ5 clock controller

["Théo Lebrun" <theo.lebrun@bootlin.com>]

Hi,

We replace fixed clocks as declared in the initial platform support
series [1] by read-only clocks exposed by the clock driver implemented
here. Write-ability is supported by the hardware but not implemented,
it could be added later-on if the need appears.

We expose ten PLLs that derive directly from the main crystal. Also, a divider
clock is exposed as a child clock of one of the PLLs.

The platform devicetree has many more clock nodes but those are
fixed-factors that are not hardware controllable; we therefore do not
deal with them.

This series starts with a fix for a fixed-rate clock registering macro that is
broken. We are the first upstream users which explains why we found the typo.

We end our patch series by adding the clock controller node to the
platform devicetree & by replacing hardcoded devicetree clocks by the
ones exposed by this driver. The controller driver addition is split in
two commits to simplify reviewing.
