This patch removes the depends on USB from all config symbols in drivers/usb/host/Kconfig and replace that with an if USB / endif block as suggested by Alan Stern. Some source ... Kconfig lines have been shuffled around to permit a better regroupment of the Kconfig files depending on "config USB" item. No functionnal change is introduced.

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
|
|
(35x, 644x ...), OMAP 243x, OMAP 3, and TUSB 6010.

Analog Devices parts using this IP include Blackfin BF54x,

BF525 and BF527.

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.
