/*
* Endpoint definitions
*
* Once enabled , pxa endpoint configuration is freezed , and cannot change
* unless a reset happens or the udc is disabled .
* Therefore , we must define all pxa potential endpoint definitions needed for
* all gadget and set them up before the udc is enabled .
*
* As the architecture chosen is fully static , meaning the pxa endpoint
* configurations are set up once and for all , we must provide a way to match
* one usb endpoint ( usb_ep ) to several pxa endpoints . The reason is that gadget
* layer autoconf doesn ' t choose the usb_ep endpoint on ( config , interface , alt )
* criteria , while the pxa architecture requires that .
*
* The solution is to define several pxa endpoints matching one usb_ep . Ex :
* - " ep1 - in " matches pxa endpoint EPA ( which is an IN ep at addr 1 , when
* the udc talks on ( config = 3 , interface = 0 , alt = 0 )
* - " ep1 - in " matches pxa endpoint EPB ( which is an IN ep at addr 1 , when
* the udc talks on ( config = 3 , interface = 0 , alt = 1 )
* - " ep1 - in " matches pxa endpoint EPC ( which is an IN ep at addr 1 , when
* the udc talks on ( config = 2 , interface = 0 , alt = 0 )
*
* We ' ll define the pxa endpoint by its index ( EPA = > idx = 1 , EPB = > idx = 2 , . . . )
