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.

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: [0, 25000000, 125000000]
default: 0
motorcomm,keep-pll-enabled:
description: |
If set, keep the PLL enabled even if there is no link. Useful if you
want to use the clock output without an ethernet link.
type: boolean
motorcomm,auto-sleep-disabled:
description: |
If set, PHY will not enter sleep mode and close AFE after unplug cable
for a timer.
type: boolean
motorcomm,tx-clk-adj-enabled:
description: |
This configuration is mainly to adapt to VF2 with JH7110 SoC.
Useful if you want to use tx-clk-xxxx-inverted to adj the delay of tx clk.
type: boolean
motorcomm,tx-clk-10-inverted:
description: |
Use original or inverted RGMII Transmit PHY Clock to drive the RGMII
Transmit PHY Clock delay train configuration when speed is 10Mbps.
type: boolean
motorcomm,tx-clk-100-inverted:
description: |
Use original or inverted RGMII Transmit PHY Clock to drive the RGMII
Transmit PHY Clock delay train configuration when speed is 100Mbps.
