+1. Rollback the sense info implementation
+        Sense buffer ptr data type in the ioctl path is reverted back
+        to u32 * as in previous versions of driver.
+
+2. Fixed the driver frame count.
+        When Driver sent wrong frame count to firmware.  As this
+        particular command is sent to drive, FW is seeing continuous
+        chip resets and so the command will timeout.
+
+3. Add the new controller(1078DE) support to the driver
+        and Increase the max_wait to 60 from 10 in the controller
+        operational status.  With this max_wait increase, driver will
+        make sure the FW will   finish the pending cmd for KDUMP case.

+/*
+ * This driver handles the USB Device Controller (UDC) in Intel's PXA 27x
+ * series processors.
+ *
+ * Such controller drivers work with a gadget driver.  The gadget driver
+ * returns descriptors, implements configuration and data protocols used
+ * by the host to interact with this device, and allocates endpoints to
+ * the different protocol interfaces.  The controller driver virtualizes
+ * usb hardware so that the gadget drivers will be more portable.
+ *
+ * This UDC hardware wants to implement a bit too much USB protocol. The
+ * biggest issues are:  that the endpoints have to be set up before the
+ * controller can be enabled (minor, and not uncommon); and each endpoint
+ * can only have one configuration, interface and alternative interface
+ * number (major, and very unusual). Once set up, these cannot be changed
+ * without a controller reset.
+ *
+ * The workaround is to setup all combinations necessary for the gadgets which
+ * will work with this driver. This is done in pxa_udc structure, statically.
+ * See pxa_udc, udc_usb_ep versus pxa_ep, and matching function find_pxa_ep.
+ * (You could modify this if needed.  Some drivers have a "fifo_mode" module
+ * parameter to facilitate such changes.)
+ *
+ * The combinations have been tested with these gadgets :
+ *  - zero gadget
+ *  - file storage gadget
+ *  - ether gadget
+ *
+ * The driver doesn't use DMA, only IO access and IRQ callbacks. No use is
+ * made of UDC's double buffering either. USB "On-The-Go" is not implemented.
+ *
+ * All the requests are handled the same way :
+ *  - the drivers tries to handle the request directly to the IO
+ *  - if the IO fifo is not big enough, the remaining is send/received in
+ *    interrupt handling.

+ *
+ * Context : when in_interrupt() or with ep->lock held
+ *
+ * Tries to transfer all pending request data into the endpoint and/or
+ * transfer all pending data in the endpoint into usb requests.
+ * Handles states of ep0 automata.
+ *
+ * PXA27x hardware handles several standard usb control requests without
+ * driver notification.  The requests fully handled by hardware are :
+ *  SET_ADDRESS, SET_FEATURE, CLEAR_FEATURE, GET_CONFIGURATION, GET_INTERFACE,
+ *  GET_STATUS
+ * The requests handled by hardware, but with irq notification are :
+ *  SYNCH_FRAME, SET_CONFIGURATION, SET_INTERFACE
+ * The remaining standard requests really handled by handle_ep0 are :
+ *  GET_DESCRIPTOR, SET_DESCRIPTOR, specific requests.
+ * Requests standardized outside of USB 2.0 chapter 9 are handled more
+ * uniformly, by gadget drivers.
+ *
+ * The control endpoint state machine is _not_ USB spec compliant, it's even
+ * hardly compliant with Intel PXA270 developers guide.
+ * The key points which inferred this state machine are :
+ *   - on every setup token, bit UDCCSR0_SA is raised and held until cleared by
+ *     software.
+ *   - on every OUT packet received, UDCCSR0_OPC is raised and held until
+ *     cleared by software.
+ *   - clearing UDCCSR0_OPC always flushes ep0. If in setup stage, never do it
+ *     before reading ep0.
+ *   - irq can be called on a "packet complete" event (opc_irq=1), while
+ *     UDCCSR0_OPC is not yet raised (delta can be as big as 100ms
+ *     from experimentation).
+ *   - as UDCCSR0_SA can be activated while in irq handling, and clearing
+ *     UDCCSR0_OPC would flush the setup data, we almost never clear UDCCSR0_OPC
+ *     => we never actually read the "status stage" packet of an IN data stage
+ *     => this is not documented in Intel documentation
+ *   - hardware as no idea of STATUS STAGE, it only handle SETUP STAGE and DATA
+ *     STAGE. The driver add STATUS STAGE to send last zero length packet in
+ *     OUT_STATUS_STAGE.
+ *   - special attention was needed for IN_STATUS_STAGE. If a packet complete
+ *     event is detected, we terminate the status stage without ackowledging the
+ *     packet (not to risk to loose a potential SETUP packet)

+ * 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, ...)
