struct_usb_ep - device side representation of USB endpoint SYNOPSIS
struct usb_ep { void * driver_data; const char * name; const struct usb_ep_ops * ops; struct list_head ep_list; unsigned maxpacket:16; unsigned max_streams:16; unsigned mult:2; unsigned maxburst:5; u8 address; const struct usb_endpoint_descriptor * desc; const struct usb_ss_ep_comp_descriptor * comp_desc; }; MEMBERS
driver_data for use by the gadget driver. name identifier for the endpoint, such as "ep-a" or "ep9in-bulk" ops Function pointers used to access hardware-specific operations. ep_list the gadget's ep_list holds all of its endpoints maxpacket The maximum packet size used on this endpoint. The initial value can sometimes be reduced (hardware allowing), according to the endpoint descriptor used to configure the endpoint. max_streams The maximum number of streams supported by this EP (0 - 16, actual number is 2^n) mult multiplier, 'mult' value for SS Isoc EPs maxburst the maximum number of bursts supported by this EP (for usb3) address used to identify the endpoint when finding descriptor that matches connection speed desc endpoint descriptor. This pointer is set before the endpoint is enabled and remains valid until the endpoint is disabled. comp_desc In case of SuperSpeed support, this is the endpoint companion descriptor that is used to configure the endpoint DESCRIPTION
the bus controller driver lists all the general purpose endpoints in gadget->ep_list. the control endpoint (gadget->ep0) is not in that list, and is accessed only in response to a driver setup callback. AUTHOR
