395 * rmii_hw_init
396 *
397 * DA850/OMAP-L138 EVM can interface to a daughter card for
398 * additional features. This card has an I2C GPIO Expander TCA6416
399 * to select the required functions like camera, RMII Ethernet,
400 * character LCD, video.
401 *
402 * Initialization of the expander involves configuring the
403 * polarity and direction of the ports. P07-P05 are used here.
404 * These ports are connected to a Mux chip which enables only one
405 * functionality at a time.
406 *
407 * For RMII phy to respond, the MII MDIO clock has to be disabled
408 * since both the PHY devices have address as zero. The MII MDIO
409 * clock is controlled via GPIO2[6].
410 *
411 * This code is valid for Beta version of the hardware
