Add Aeonsemi PHYs and the requirement of a firmware to correctly work. Also document the max number of LEDs supported and what PHY ID expose when no firmware is loaded. Supported PHYs AS21011JB1, AS21011PB1, AS21010JB1, AS21010PB1, AS21511JB1, AS21511PB1, AS21510JB1, AS21510PB1, AS21210JB1, AS21210PB1 that all register with the PHY ID 0x7500 0x9410 on C45 registers before the firmware is loaded.

Aeonsemi AS21xxx Ethernet PHYs requires a firmware to be loaded to actually
|
|
work. The same firmware is compatible with various PHYs of the same family.
|
|
|
|
A PHY with not firmware loaded will be exposed on the MDIO bus with ID
|
|
0x7500 0x7500 or 0x7500 0x9410 on C45 registers.
|
|
|
|
This can be done and is implemented by OEM in 2 different way:
|
|
- Attached SPI flash directly to the PHY with the firmware. The PHY
|
|
will self load the firmware in the presence of this configuration.
|
|
- Manually provided firmware loaded from a file in the filesystem.
|
|
|
|
Each PHY can support up to 5 LEDs.
