The way is to mark them as critical, so I do not think you provided accurate rationale for bindings change. Best regards, Krzysztof

Thanks for the suggestion Stephen, will handle this way in V2. Between, I think still the entries in the dt-bindings can be dropped along with the entries in the clock table?

gcc_snoc_nssnoc_clk, gcc_snoc_nssnoc_1_clk, gcc_nssnoc_nsscc_clk are enabled by default and it's RCG is properly configured by bootloader. Some of the NSS clocks needs these clocks to be enabled. To avoid these clocks being disabled by clock framework, drop these entries.
