 * of_get_phy_mode - Get phy mode for given device_node
 * @np: Pointer to the given device_node
 * The function gets phy interface string from property 'phy-mode' or
 * 'phy-connection-type', and return its index in phy_modes table, or errno in
 * error case.

/** * Search the device tree for the best MAC address to use. 'mac-address' is * checked first, because that is supposed to contain to "most recent" MAC * address. If that isn't set, then 'local-mac-address' is checked next, * because that is the default address. If that isn't set, then the obsolete * 'address' is checked, just in case we're using an old device tree. * * Note that the 'address' property is supposed to contain a virtual address of * the register set, but some DTS files have redefined that property to be the * MAC address. * * All-zero MAC addresses are rejected, because those could be properties that * exist in the device tree, but were not set by U-Boot. For example, the * DTS could define 'mac-address' and 'local-mac-address', with zero MAC * addresses. Some older U-Boots only initialized 'local-mac-address'. In * this case, the real MAC is in 'local-mac-address', and 'mac-address' exists * but is all zeros. */
