526 * the enet controller is resumed. This code makes sure the phy

528 * the enet controller depends on an active phy clock to complete
529 * a DMA reset. A DMA reset will "time out" if executed
530 * with no phy clock input on the Synopsys enet controller.
531 * Verified through Synopsys Case #8000711656.
532 *
533 * Note that the phy clock is also gated when the phy is isolated.
534 * Phy "suspend" and "isolate" controls are located in phy basic
535 * control register 0, and can be modified by the phy driver
536 * framework.
