Commit Message

Matwey V. Kornilov April 28, 2020, 10:03 a.m. UTC
There are at least two different versions existing for MYIR Zturn:

 * v4 schematics has Atheros AR8035 PHY at 0b000
     http://www.myirtech.com/download/Zynq7000/Z-TURNBOARD_schematic.pdf
 * v5 schematics has Micrel KSZ9031 PHY at 0b011
     v5 schematics available at DVD disk supplied with the board

Specify both PHYs to make ethernet interface working for any board
revision. This commit relies on of_mdiobus_register() behavior.
When phy-handle is missed, every nested PHY node is considered,
while ENODEVs are ignored.

Before the patch:

[   28.295002] macb e000b000.ethernet eth0: Could not attach PHY (-19)

After the patch:

[   28.257365] macb e000b000.ethernet eth0: PHY [e000b000.ethernet-ffffffff:00] driver [Micrel KSZ9031 Gigabit PHY] (irq=POLL)
[   28.257384] macb e000b000.ethernet eth0: configuring for phy/rgmii-id link mode

Are you pinging me or Anton?
I really want another person to test this patch.
If there is none else who can test it I think it is time to remove
support for this board.

Thanks,
Michal
