23 RGMII RX Clock Delay used only when PHY operates in RGMII mode with
24 internal delay (phy-mode is 'rgmii-id' or 'rgmii-rxid') in pico-seconds.
25 enum: [ 0, 150, 300, 450, 600, 750, 900, 1050, 1200, 1350, 1500, 1650,
26 1800, 1900, 1950, 2050, 2100, 2200, 2250, 2350, 2500, 2650, 2800,
27 2950, 3100, 3250, 3400, 3550, 3700, 3850, 4000, 4150 ]
32 RGMII TX Clock Delay used only when PHY operates in RGMII mode with
33 internal delay (phy-mode is 'rgmii-id' or 'rgmii-txid') in pico-seconds.
34 enum: [ 0, 150, 300, 450, 600, 750, 900, 1050, 1200, 1350, 1500, 1650, 1800,
38 motorcomm,clk-out-frequency-hz:
39 description: clock output on clock output pin.
40 enum: [0, 25000000, 125000000]
43 motorcomm,keep-pll-enabled:
45 If set, keep the PLL enabled even if there is no link. Useful if you
46 want to use the clock output without an ethernet link.
49 motorcomm,auto-sleep-disabled:
51 If set, PHY will not enter sleep mode and close AFE after unplug cable
55 motorcomm,tx-clk-adj-enabled:
57 This configuration is mainly to adapt to VF2 with JH7110 SoC.
58 Useful if you want to use tx-clk-xxxx-inverted to adj the delay of tx clk.
61 motorcomm,tx-clk-10-inverted:
63 Use original or inverted RGMII Transmit PHY Clock to drive the RGMII
64 Transmit PHY Clock delay train configuration when speed is 10Mbps.
67 motorcomm,tx-clk-100-inverted:
69 Use original or inverted RGMII Transmit PHY Clock to drive the RGMII
70 Transmit PHY Clock delay train configuration when speed is 100Mbps.
73 motorcomm,tx-clk-1000-inverted:
75 Use original or inverted RGMII Transmit PHY Clock to drive the RGMII
76 Transmit PHY Clock delay train configuration when speed is 1000Mbps.
