But I do agree that it does what it says on the box. It's not needed to build or load the driver, but the PHY won't function at all without reading values from the SoCs efuse, and for that the nvmem driver is required. Using a simple dependency instead of select will fix it. Reviewed-by: Daniel Golle <daniel@makrotopia.org> > > Reviewed-by: Simon Horman <simon.horman@corigine.com> > >
