> The opp_supported_hw DT property allows the DT to specify a mask of chip
> revisions that a certain OPP is eligible for. This allows for easy
> limiting of maximum frequencies, for instance.
> 
> Add support for that in the sun50i-cpufreq-nvmem driver. We support both
> the existing opp-microvolt suffix properties as well as the
> opp-supported-hw property, the generic code figures out which is needed
> automatically.
> However if none of the DT OPP nodes contain an opp-supported-hw
> property, the core code will ignore all OPPs and the driver will fail
> probing. So check the DT's eligibility first before using that feature.
