* update_pxa_ep_matches - update pxa_ep cached values in all udc_usb_ep
* @udc: pxa udc
*
- * Context: in_interrupt()
+ * Context: interrupt handler
*
* Updates all pxa_ep fields in udc_usb_ep structures, if this field was
* previously set up (and is not NULL). The update is necessary is a
* @ep: pxa physical endpoint
* @req: usb request
*
- * Context: callable when in_interrupt()
+ * Context: interrupt handler
*
* Unload as many packets as possible from the fifo we use for usb OUT
* transfers and put them into the request. Caller should have made sure
* @ep: control endpoint
* @req: request
*
- * Context: callable when in_interrupt()
+ * Context: interrupt handler
*
* Sends a request (or a part of the request) to the control endpoint (ep0 in).
* If the request doesn't fit, the remaining part will be sent from irq.
* @_req: usb request
* @gfp_flags: flags
*
- * Context: normally called when !in_interrupt, but callable when in_interrupt()
- * in the special case of ep0 setup :
+ * Context: thread context or from the interrupt handler in the
+ * special case of ep0 setup :
* (irq->handle_ep0_ctrl_req->gadget_setup->pxa_ep_queue)
*
* Returns 0 if succedeed, error otherwise
* pxa_udc_pullup - Offer manual D+ pullup control
* @_gadget: usb gadget using the control
* @is_active: 0 if disconnect, else connect D+ pullup resistor
- * Context: !in_interrupt()
+ *
+ * Context: task context, might sleep
*
* Returns 0 if OK, -EOPNOTSUPP if udc driver doesn't handle D+ pullup
*/
* @_gadget: usb gadget
* @mA: current drawn
*
- * Context: !in_interrupt()
+ * Context: task context, might sleep
*
* Called after a configuration was chosen by a USB host, to inform how much
* current can be drawn by the device from VBus line.
* @fifo_irq: 1 if triggered by fifo service type irq
* @opc_irq: 1 if triggered by output packet complete type irq
*
- * Context : when in_interrupt() or with ep->lock held
+ * Context : interrupt handler

*
- * Is always called when in_interrupt() and with ep->lock released.
+ * Is always called from the interrupt handler. ep->lock must not be held.
