Quoting Rajendra Nayak (2021-07-16 03:00:58)
> qup-i2c devices on sc7180 are clocked with a fixed clock (19.2 MHz)
> Though qup-i2c does not support DVFS, it still needs to vote for a
> performance state on 'CX' to satisfy the 19.2 Mhz clock frequency
> requirement.
>
> Use 'required-opps' to pass this information from
> device tree, and also add the power-domains property to specify
> the CX power-domain.
