Merge patch series "net: dwc_eth_qos: Add glue driver for Intel MAC"
Philip Oberfichtner <pro@denx.de> says:
This patch series implements the dwc_eth_qos glue driver for Intel SOCs.
Before doing that, a few general adaptions to the dwc_eth_qos.c main
driver are required. Most notably, the preparation for PCI based driver
instances, which do not necessarily use a device tree.
