| 2 | |
| 3 | Required properties: |
| 4 | - reg - The ID number for the phy, usually a small integer |
| 5 | - ti,rx-internal-delay - RGMII Recieve Clock Delay - see dt-bindings/net/ti-dp83867.h |
| 6 | for applicable values |
| 7 | - ti,tx-internal-delay - RGMII Transmit Clock Delay - see dt-bindings/net/ti-dp83867.h |
| 8 | for applicable values |
| 9 | - ti,fifo-depth - Transmitt FIFO depth- see dt-bindings/net/ti-dp83867.h |
| 10 | for applicable values |
| Janine Hagemann | ed51bfc | 2018-08-28 08:25:37 +0200 | [diff] [blame] | 11 | - enet-phy-lane-swap - Indicates that PHY will swap the TX/RX lanes to |
| 12 | compensate for the board being designed with the lanes swapped. |
| 13 | - enet-phy-no-lane-swap - Indicates that PHY will disable swap of the |
| 14 | TX/RX lanes. |
| Grygorii Strashko | a5efed6 | 2019-11-18 23:04:42 +0200 | [diff] [blame] | 15 | - ti,clk-output-sel - Muxing option for CLK_OUT pin. See dt-bindings/net/ti-dp83867.h |
| 16 | for applicable values. The CLK_OUT pin can also |
| 17 | be disabled by this property. When omitted, the |
| 18 | PHY's default will be left as is. |
