-Subject: [PATCH] of: net: fix of_get_mac_addr_nvmem() for non-platform devices
-
-of_get_mac_address() already supports fetching the MAC address by an
-nvmem provider. But until now, it was just working for platform devices.
-Esp. it was not working for DSA ports and PCI devices. It gets more
-common that PCI devices have a device tree binding since SoCs contain
-integrated root complexes.
-
-Use the nvmem of_* binding to fetch the nvmem cells by a struct
-device_node. We still have to try to read the cell by device first
-because there might be a nvmem_cell_lookup associated with that device.
