TSE MAC and Marvell 88E1111

--- Quote Start ---

The TSE is able to communicate with up to two PHYs through MDIO. You need first to set up the MDIO address of the PHY, with one of those calls:

IOWR_ALTERA_TSEMAC_MDIO_ADDR0(base,data)
IOWR_ALTERA_TSEMAC_MDIO_ADDR1(base,data)

Obviously the first line sets the MDIO address for the PHY number 0 and the second one sets the MDIO address for the PHY number 1. base is tse_mac_base, as you guessed, and data is the MDIO address.

Then you can access the register with one of those calls:

IORD_ALTERA_TSEMAC_MDIO(base, mdio, reg_num)
IOWR_ALTERA_TSEMAC_MDIO(base, mdio, reg_num, data)

The first line reads, the second writes. base is again tse_mac_base, mdio is the PHY number (0 or 1, depending on the call you used to set up the MDIO address), reg_num the MDIO register number, and data is the value to write.

Hi,

I'd like to connect one TSE with two Marvell PHYs:

1- Are the above Macros are all that we need?

2- How we are going to connect the MDIO & MDC to both PHY devices?

Your prompt response is highly appreciated.

Thanks & Regards.
