一、经过调试， LAN8710A在 am335x 上面需要使用 GMII的模式，设备树 pin mux配置如下：

// 下面是工作模式的配置，在睡眠模式下是配成GPIO模式
162     cpsw_default: cpsw_default {
163         pinctrl-single,pins = <
164             /* Slave 1 */
165             0x110 ( PIN_INPUT_PULLDOWN | MUX_MODE0 )    /* (J15) gmii1_rxer */
166             0x114 ( PIN_OUTPUT         | MUX_MODE0 )    /* (J16) gmii1_txen */
167             0x118 ( PIN_INPUT_PULLDOWN | MUX_MODE0 )    /* (J17) gmii1_rxdv */
168             0x11c ( PIN_OUTPUT         | MUX_MODE0 )    /* (J18) gmii1_txd3 */
169             0x120 ( PIN_OUTPUT         | MUX_MODE0 )    /* (K15) gmii1_txd2 */
170             0x124 ( PIN_OUTPUT         | MUX_MODE0 )    /* (K16) gmii1_txd1 */
171             0x128 ( PIN_OUTPUT         | MUX_MODE0 )    /* (K17) gmii1_txd0 */
172             0x12c ( PIN_INPUT_PULLDOWN | MUX_MODE0 )    /* (K18) gmii1_txclk */
173             0x130 ( PIN_INPUT_PULLDOWN | MUX_MODE0 )    /* (L18) gmii1_rxclk */
174             0x134 ( PIN_INPUT_PULLDOWN | MUX_MODE0 )    /* (L17) gmii1_rxd3 */
175             0x138 ( PIN_INPUT_PULLDOWN | MUX_MODE0 )    /* (L16) gmii1_rxd2 */
176             0x13c ( PIN_INPUT_PULLDOWN | MUX_MODE0 )    /* (L15) gmii1_rxd1 */
177             0x140 ( PIN_INPUT_PULLDOWN | MUX_MODE0 )    /* (M16) gmii1_rxd0 */
178             0x74 ( PIN_INPUT_PULLDOWN  | MUX_MODE1 )    /* (U17) gpmc_wpn.gmii2_rxerr */
179             0x40 ( PIN_OUTPUT          | MUX_MODE1 )    /* (R13) gpmc_a0.gmii2_txen */
180             0x44 ( PIN_INPUT_PULLDOWN  | MUX_MODE1 )    /* (V14) gpmc_a1.gmii2_rxdv */
181             0x58 ( PIN_INPUT_PULLDOWN  | MUX_MODE1 )    /* (U15) gpmc_a6.gmii2_txclk */
182             0x5c ( PIN_INPUT_PULLDOWN  | MUX_MODE1 )    /* (T15) gpmc_a7.gmii2_rxclk */
183             0x54 ( PIN_OUTPUT          | MUX_MODE1 )    /* (V15) gpmc_a5.gmii2_txd0 */
184             0x50 ( PIN_OUTPUT          | MUX_MODE1 )    /* (R14) gpmc_a4.gmii2_txd1 */
185             0x4c ( PIN_OUTPUT          | MUX_MODE1 )    /* (T14) gpmc_a3.gmii2_txd2 */
186             0x48 ( PIN_OUTPUT          | MUX_MODE1 )    /* (U14) gpmc_a2.gmii2_txd3 */
187             0x6c ( PIN_INPUT           | MUX_MODE1 )    /* (V17) gpmc_a11.gmii2_rxd0 */
188             0x68 ( PIN_INPUT           | MUX_MODE1 )    /* (T16) gpmc_a10.gmii2_rxd1 */
189             0x64 ( PIN_INPUT           | MUX_MODE1 )    /* (U16) gpmc_a9.gmii2_rxd2 */
190             0x60 ( PIN_INPUT           | MUX_MODE1 )    /* (V16) gpmc_a8.gmii2_rxd3 */
191         >;
192     };

二、有关节点的配置如下：

595 &mac {
596     pinctrl-names = "default", "sleep";
597     pinctrl-0 = <&cpsw_default>;
598     pinctrl-1 = <&cpsw_sleep>;
599     dual_emac = <1>;
600     status = "okay";
601 };
602
603 &davinci_mdio {
604     pinctrl-names = "default", "sleep";
605     pinctrl-0 = <&davinci_mdio_default>;
606     pinctrl-1 = <&davinci_mdio_sleep>;
607     status = "okay";
608 };
609
610 &cpsw_emac0 {
611     phy_id = <&davinci_mdio>, <0>;
612     phy-mode = "mii";
613     dual_emac_res_vlan = <1>;
614 };
615
616 &cpsw_emac1 {
617     phy_id = <&davinci_mdio>, <1>;
618     phy-mode = "mii";
619     dual_emac_res_vlan = <2>;
620 };
