Marvell 88E1548P Linux driver for T2081 processor

francescocaiazz — Mon, 24 Jul 2017 13:47:37 GMT

Hello,

I'm looking for the device drivers of the Marvell Alaska 88E1548P PHY for T2081 processor (Uses SGMII interface), mounted on a custom board I'm working on.

Actually I'm developing my application on a T2080RDB-PC dev. board, which uses RGMII interface in order to use its PHY chip. With some researches I couldn't find anything usefull.

Thanks.

Usually it is not needed. The T2081RDB board uses the RTL8211E in RGMII mode also.

Compare registers of the RTL8211E and the Marvell Alaska 88E1548P.

Have a great day,

Hi,

the main difference relates the interface used to connect with the PHY chip.

While the T2081RDB has the processor interfaced with the PHY chip through the RGMII ports, the custom board I'm working on uses the SGMII interfaces.

How could I customize the existing drivers in order to accommodate this interface difference?
