[v6,0/7] clk: qcom: add camera clock controller driver for SM8450 SoC

The patchset adds support of a camera clock controller found on
QCOM SM8450 SoC, noticeably a camcc pll2 is a new "rivian evo"
type of pll, its generic support is added in the series.

Note that SM8450 ES variant has a slightly different configurtion,
the published version is intended to support SM8450 CS SoC.

Changes from v5 to v6:
* rebased on top of linux-next,
* added Rob's tag,
* fixed a topology of power domains around titan_top.

Changes from v4 to v5:
* fixed the same typo in a usage example found in yaml file as in v3
  change.

Changes from v3 to v4:
* fixed a changed path in the yaml file.

Changes from v2 to v3:
* fixed a typo in a usage example found in yaml file,
* renamed dt related files to match the compatible "qcom,sm8450-camcc",
* minor fixes in the driver per review requests from Bjorn,
* added Bjorn's tag to a change of exported symbols namespace.

Changes from v1 to v2:
* updated qcom,camcc-sm8450.yaml according to review comments from Rob,
* changed qcom,camcc-sm8450.h licence to dual one,
* disabled camcc device tree node by default,
* added Stephen's tag,
* rebased the series on top of clk-for-5.18

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.
