In our SoC current architecture there are multiple sdio buses, basically
one for each MAC.
Neverthelees this architecture might change in the future.
Moreover, I agree that driver should be generic, so I guess that we
might add a phy_addr field
in the device structure and pass it thru the initialize routine, as the
macb driver is doing.
In the meantime I saw that Vipin already provided a V2 of the driver,
which is still in the old
way.
Vipin, can you possibly provide your comments?
Thanks,
Arm
