Merge branch 'lan78xx-Read-configuration-from-Device-Tree'
Phil Elwell says:
====================
lan78xx: Read configuration from Device Tree
The Microchip LAN78XX family of devices are Ethernet controllers with
a USB interface. Despite being discoverable devices it can be useful to
be able to configure them from Device Tree, particularly in low-cost
applications without an EEPROM or programmed OTP.
This patch set adds support for reading the MAC address and LED modes from
Device Tree.
v4:
- Rename nodes in bindings doc.
v3:
- Move LED setting into PHY driver.
v2:
- Use eth_platform_get_mac_address.
- Support up to 4 LEDs, and move LED mode constants into dt-bindings header.
- Improve bindings document.
- Remove EEE support.
