For OMAP4 at least, this is something that is probably' best left up to the board to select. For the davinci's and blackfins, they don't have an option. They have a fully transparent internal PHY which doesn't need any configuring. However, with the OMAP4, you could potentially use an external ULPI transceiver. This can be another transparent PHY for which we could select the NOP_XCEIV. Or it could be something like the PHY in the TWL5030 which may need configuring over an I2C interface. - Anand -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
