Subject: [PATCH net-next 1/5] net: dt-bindings: Introduce the Qualcomm IPQESS Ethernet switch
Add the DT binding for the IPQESS Ethernet switch subsystem, that
integrates a modified QCA8K switch and an EDMA MAC controller. It inherits
from a basic ethernet switch binding and adds three regmaps, a phandle and
reset line for the PSGMII, a phandle to the MDIO bus, a clock, and 32
interrupts.
