A recent bug fix I did that was marked for stable backports
introduced a slightly wrong dependency on CONFIG_OMAP_CONTROL_PHY.
I was missing the fact that the PHY driver already stubs out the
omap_control_usb_set_mode, and we only need to add a dependency
to prevent the musb-omap2430 driver from being built-in when
the phy driver is a loadable module, but we should not prevent it
from being built altogether when the phy driver is disabled.

Say Y here if your system has a dual role high speed USB
|
|
controller based on the Mentor Graphics silicon IP. Then
|
|
configure options to match your silicon and the board
|
|
it's being used with, including the USB peripheral role,
|
|
or the USB host role, or both.

Do not choose this unless DMA support for your SOC or board
|
|
is unavailable (or unstable). When DMA is enabled at compile time,
|
|
you can still disable it at run time using the "use_dma=n" module
|

parameter.
