am335x lan8710改rmii连接， ping不通

图片掉了，文字回复：
mux：
static struct module_pin_mux rmii1_pin_mux[] = {
{OFFSET(mdio_clk), MODE(0) | PULLUP_EN}, /* MDIO_CLK */
{OFFSET(mdio_data), MODE(0) | RXACTIVE | PULLUP_EN}, /* MDIO_DATA */
{OFFSET(mii1_crs), MODE(1) | RXACTIVE}, /* MII1_CRS */
{OFFSET(mii1_rxerr), MODE(1) | RXACTIVE}, /* MII1_RXERR */
{OFFSET(mii1_txen), MODE(1)}, /* MII1_TXEN */
{OFFSET(mii1_txd1), MODE(1)}, /* MII1_TXD1 */
{OFFSET(mii1_txd0), MODE(1)}, /* MII1_TXD0 */
{OFFSET(mii1_rxd1), MODE(1) | RXACTIVE}, /* MII1_RXD1 */
{OFFSET(mii1_rxd0), MODE(1) | RXACTIVE}, /* MII1_RXD0 */
{OFFSET(rmii1_refclk), MODE(0) | RXACTIVE}, /* RMII1_REFCLK */
{-1},
};

rmii设置
writel(RMII_MODE_ENABLE | RMII_CHIPCKL_ENABLE, &cdev->miisel);
cpsw_slaves[0].phy_if = PHY_INTERFACE_MODE_RMII;
cpsw_slaves[1].phy_if = PHY_INTERFACE_MODE_RMII;

建议DUMP一下PHY的寄存器分析一下
