The OPP core will use this phandle to find the operating points for the device. +This can contain more than one phandle for power domain providers that provide +multiple power domains. That is, one phandle for each power domain. If only one +phandle is available, then the same OPP table will be used for all power domains +provided by the power domain provider. + If required, this can be extended for SoC vendor specific bindings. Such bindings should be documented as Documentation/devicetree/bindings/power/<vendor>-opp.txt and should have a compatible description like: "operating-points-v2-<vendor>". |
