[v3]
  * Add clocks/clock-names required for the MSS clock controller.
  * Add pm_ops to enable/disable the required dependent clock.
  * Add parent_data for the MSS clocks.
  * Update the GCC MSS clocks from _CBCR to _CLK.

[v2]
  * Update the license for the documentation and fix minor comments in the
    YAML bindings.

[v1]
  * Add driver support for Modem clock controller for SC7180 and also
    update device tree bindings for the various clocks supported in the
    clock controller.

The Modem Subsystem clock provider have a bunch of generic properties
that are needed in a device tree. Add a YAML schemas for those.

Add support for the modem clock controller found on SC7180
based devices. This would allow modem drivers to probe and
control their clocks.

Can you point to the header file from here?
include/dt-bindings/clock/qcom,sc7180-mss.h I guess.

Why is it optional? Don't these all go there?

Do these really need _clk at the end? Seems redundant.

we don't seem to be referencing the
mss_mfab_axi and mss_nav_axi in the
mss clk driver though, do we really
need them in bindings? If we dont
can we drop the clock-names as well.

They are linked as parent for the clocks. So we need them.
