Hi anyone:
I found in RM of imx7d, some MII interface PIN is missing or wrong.
example:

TX_CLK should be use as input ,but in RM it's ouput.
and there is no ENET1_TX_EN pin.
RGMII_TX_CTL is similar to TX_EN, but it used for RGMII only

Does anyone know the detail of pin assignment for MII interface?
MII interface should contains the following pins:
TXD[0:3] TX_ER TX_CLK/TXC TX_EN RXD[0:3] RX_CLK RX RX_XDV COL CRS
