A clock controller could be connected to single or multiple power domains. Add support for powerdomain_class which would help associate these power domains to the RCGs and PLLs in the clock controller. Map the domain and the corresponding frequencies to the clock(RCG/PLL). The clock frequency request from a consumer would be mapped to the corresponding performance corner, aggregated at the clock driver and would be vote/unvoted to the genpd framework for the desired performance state. This series add an example of power domain class for sdm845 RCG/PLLs and the corresponding frequency mappings. This depends on power domain drivers of SDM845 https://lkml.org/lkml/2018/6/27/7.
