Alexander,

I agree with you that it can get difficult with users. But it is best for
users do not disable anything they are not familiar with.

As the USB_PHY option doesn't depend on anything, it is safe to select it
from USB_EHCI_HCD_OMAP.

However, the PHY drivers themselves must be selected from the board configs.

Maybe I understood something wrong, but if the OMAP USB driver requires CONFIG_USB_PHY (or similiar), it should be selected automatically and not just enabled in the board config.

I just had it to often, that I needed to search around why a driver doesn't work (or even compiles), just to find out that I need to enable some strange config option which wasn't selected automatically. Especially with OMAPs. ;)

And this not only occured when disabling options, it often occured by just updating the kernel. Suddenly some obscur option was needed too, it wasn't selected automatically by make oldconfig, bang. So the argument to not remove anything from a board config doesn't help much.

Sorry for the rant. ;)

Regards,

Alexander
