Subject: [PATCH v2 0/2] Add device-tree support for CPSW9G on J721E SoC

Hello,

This series adds the device-tree nodes for CPSW9G instance of CPSW
Ethernet Switch on TI's J721E SoC. Additionally, an overlay file is also
added to enable CPSW9G nodes in QSGMII mode with the Add-On J7 QUAD Port
Ethernet expansion QSGMII daughtercard.

---
Changes from v1:
1. Rename node name "mdio_pins_default" to "mdio0-pins-default", since
   node names shouldn't contain underscores.
2. Change node label "mdio_pins_default" to "mdio0_pins_default".

The reason for adding 0 after mdio with the above changes, is to indicate
the association of the cpsw0 instance of CPSW with this instance of MDIO.

v1:
