Since commit df4fdd0db475 ("dt-bindings: firmware: arm,scmi: Restrict protocol child node properties") the following dtbs_check warning is shown:
rk3588-rock-5b.dtb: scmi: protocol@14: Unevaluated properties are not allowed ('assigned-clock-rates', 'assigned-clocks' were unexpected)
I think that's a somewhat questionable use of assigned-clock-rates. It should be located with the consumer rather than the provider IMO. The consumers of those 2 clocks are the CPU nodes.
Agreed. We definitely don't use those in the scmi clk provider driver. So NACK for the generic SCMI binding change.
According to [1], "configuration of common clocks, which affect multiple consumer devices can be similarly specified in the clock provider node".
True, but in this case it's really a single consumer because it's all CPU nodes which are managed together.
That would avoid duplicating assigned-clock-rates in the CPU nodes.
Wouldn't one node be sufficient?
Thinking more about this, why aren't you using OPP tables to define CPU frequencies. Assigned-clocks looks like a temporary hack because you haven't done proper OPP tables.
