RGMII RX Clock Delay used only when PHY operates in RGMII mode with
internal delay (phy-mode is 'rgmii-id' or 'rgmii-rxid') in pico-seconds.
enum: [ 1600, 1800, 2000, 2200, 2400 ]
default: 2000

RGMII TX Clock Delay used only when PHY operates in RGMII mode with
internal delay (phy-mode is 'rgmii-id' or 'rgmii-txid') in pico-seconds.
enum: [ 1600, 1800, 2000, 2200, 2400 ]
default: 2000
adi,fifo-depth-bits:
description: |
When operating in RMII mode, this option configures the FIFO depth.
enum: [ 4, 8, 12, 16, 20, 24 ]
default: 8
adi,phy-output-clock:
description: |
Select clock output on GP_CLK pin. Two clocks are available:
A 25MHz reference and a free-running 125MHz.
The phy can alternatively automatically switch between the reference and
the 125MHz clocks based on its internal state.
