'default' on a choice refers to the symbol selected by default, not to the choice mode, so 'default n' is meaningless. No functional changes. Optional choices implicitly default to n mode (and there is no way to make them default to another mode). Discovered in Kconfiglib (https://github.com/ulfalizer/Kconfiglib), which prints the following warning: warning: the default selection n (undefined) of <choice> (defined at drivers/usb/ulpi/Kconfig:3) is not contained in the choice I've added a corresponding warning to the C tools too, which is currently in linux-next: https://patchwork.kernel.org/patch/9983667/ Signed-off-by: Ulf Magnusson <ulfalizer@gmail.com>

Select to commnicate with USB PHY via ULPI interface.
|

ULPI is wrapper on UTMI+ core that is used as
|
|
PHY Transreceiver for USB controllers.
|
|
|
|
This driver uses ULPI viewports that are specific for each SoC.
