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.

Texas Instruments families using this IP include DaVinci

Analog Devices parts using this IP include Blackfin BF54x,

If you do not know what this is, please say N.

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.
