The way we enable ULPI support today isn't something that should work. The "optional" keyword in a choice statement is not a documented feature. To make this work in a supported way, make USB_ULPI something we ask about if USB_HOST is set. Next, we move the choice of what viewer to use to be after the framework portion and to depend on that. We then borrow a few words from the top-level README to make the help text here clearer. Finally we make the Qualcomm driver select ULPI as it's required and we make the tegra driver not duplicate a check that Kconfig now handles for us. Signed-off-by: Tom Rini <trini@konsulko.com>

Select to commnicate with USB PHY via ULPI interface.

The ULPI (UTMI Low Pin (count) Interface) is a wrapper on UTMI+ core
|
|
that is used as PHY Transreceiver for USB controllers.
|
|
|
|
This driver uses ULPI viewports that are specific for each SoC.
