Sorry to come into the binding part at so late stage. I just
got a request for i.MX95 SCMI CLK a few days ago which is impossible
for vendor specific properties.

But I am not sure "assigned-clock-sscs" is welcomed by maintainers.
Please also help to check whether this is usable for your patches
to enable SSC for i.MX8M PLL.

Not intend to waste to your effort.
I also replied in the PR to express my apologize. 

Thanks,
Peng.
