bool "USB Physical Layer drivers"
- USB controllers (those which are host, device or DRD) need a
- device to handle the physical layer signalling, commonly called
- a PHY.
+ 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 following drivers add support for such PHY devices.
+ 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.
