porting sdio driver for marvell

shraddha
Prodigy 10 points

I have to port a Marvel 8686 driver from Gemtek to DM355.

i also downloaded and applied the sdio patches for Atheros from TI website.

I am wondering how to start.

Because the driver source which I got for Marvel is for PXA platform.

So I was confused whether to change the atheros driver for marvel.

Or the marvel driver source code for DM355.

what i feel is changing the marvel driver is more feasible,

it would be helpful if anybody has already done porting of marvel wifi drivers to DM355.

or is there any documentation or porting guide for the atheros driver

    I would agree with the idea of porting the Marvel driver from the PXA platform to the DM355.  Generally speaking, if both the Atheros and Marvell chipsets support a SDIO interface, you should concentrate the porting effort to the differences in implementation of the SDIO interface between the PXA and DM355.
    If this is a WLAN chipset, which I assume it is, the driver for Marvell should go with the Marvell chipset and similarly for Atheros.  The layer to modify is the physical layer implementation which is the more common ground, ie. the SDIO interface.

    I'm not aware of any effort, but that doesn't mean it hasn't happened.

    I would not suggest going down this route.
