> Currently firmware is maintaining CCF specific flags and provides to CCF as it
> is. But CCF flag numbers may change and that shouldn't mean that the
> firmware needs to change. The firmware should have its own 'flag number
> space' that is distinct from the common clk framework's 'flag number space'.
> So use firmware specific clock flags in ZynqMP clock driver instead of CCF
> flags.

> Changes in v3:
> - Modify helper function signature to map zynqmp (common)flags with CCF
> - Add helper function to map zynqmp (mux & divider)flags with CCF flags
>
> Changes in v2:
> - Add helper function to map zynqmp (common)flags with CCF flags.
> - Mapped zynqmp clock flags with CCF flags from
> zynqmp_clk_register_*() functions instead of
> __zynqmp_clock_get_topology() which is changing the flags to struct
> clk_init_data instead of the struct clock_topology.
