usb: phy: make PHY driver selection possible by controller drivers
Convert PHY Drivers from menuconfig to menu so that the PHY drivers can be explicitely selected by the controller drivers. USB_PHY is no longer a user visible option. It is upto to the PHY drivers to select it if needed. This patch does so for the existing PHY drivers that use the USB_PHY library. Doing so moves the USB_PHY and PHY driver selection problem from the end user to the PHY and controller driver developer. e.g. Earlier, a controller driver (e.g. EHCI_OMAP) that needs to select a PHY driver (e.g. NOP_PHY) couldn't do so because the PHY driver depended on USB_PHY. Making the controller driver depend on USB_PHY has a negative effect i.e. it becomes invisible to the user till USB_PHY is enabled. Most end users will not familiar with this. With this patch, the end user just needs to select the controller driver needed for his/her platform without worrying about which PHY driver to select. Also update USB_EHCI_MSM, USB_LPC32XX and USB_OMAP to not depend on USB_PHY any more. They can safely select the necessary PHY drivers. [ balbi@ti.com : refreshed on top of my next branch.

- bool "USB Physical Layer drivers"
- help
- Most USB controllers have the physical layer signalling part
- (commonly called a PHY) built in. However, dual-role devices
- (a.k.a. USB on-the-go) which support being USB master or slave
- with the same connector often use an external PHY.
-
- The drivers in this submenu add support for such PHY devices.
- They are not needed for standard master-only (or the vast
- majority of slave-only) USB interfaces.
-
- If you're not sure if this applies to you, it probably doesn't;
- say N here.
