[v5]
 * Update the clock ID for GCC_MSS_NAV_AXIS_CLK to GCC_MSS_NAV_AXI_CLK

[v4]
 * Split the GCC MSS clocks and Modem clock driver.
 * Update mss_regmap_config to const.
 * Rename the Documentation binding as per the latest convention.
 * Minor comments of clock-names/clocks properties updated.

[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.

The error shows syntax error at line 21, below is the example.dts from 
my tree and would compile for me as I have the dependency of the include 
file when I compile.

Please guide how to go about.

+#define GCC_MSS_MFAB_AXIS_CLK					126

  17 #include <dt-bindings/clock/qcom,gcc-sc7180.h>
  18         clock-controller@41a8000 {
  19           compatible = "qcom,sc7180-mss";
  20           reg = <0 0x041a8000 0 0x8000>;
  21           clocks = <&gcc GCC_MSS_MFAB_AXIS_CLK>,

The header should be part of this patch if possible.

And here, so that it matches the binding.

I have combined all the bindings in the same patch to avoid any YAML 
dependency.
