On CDNS3 usb, the IOC interrupt for IN is triggered when data
move from memory to FIFO, but not for the transfer completion.When running fastboot command "continue" to disconnect USB device.
The last message "OKAY" sent from device setups a callback to IOC
interrupt handler and disconnect with host in this callback.
However, the real transfer hasn't finished due to host doesn't send
IN at that time, it causes the error at host side.This patch will reset all enabled endpoints in pull up before disable
the device mode. The reset checks the EP_STS.BUFFEREMPTY bit to ensure
data has sent to host.Signed-off-by: Ye Li

On 2019.04 SPL, we enabled DM gadget driver for QM/QXP to support
dual USB ports. The CI_UDC DM gadget driver will call init function
inside EHCI mx6 driver, so when building SPL on iMX8QM/QXP with CI UDC
enabled, we have to enable usb host driver as well, and this introduces
about more than 40KB size to SPL.Move the common codes to a independent file, so that both host driver
and gadget driver can call it, then decouple the host and gadget driver.Note: the patch only applies to ci_udc gadget DM driver. For non-DM gadget
driver, it still depends ehci host interfaces.Signed-off-by: Ye Li

- Advantage of park mode
When only a single Async endpoint is active.- Behavior of park mode
1. The controller prefetches data/TRBs to do 3 * burst_size worth
of packets.
2. When park mode is disabled there will be some delay between
bursts on the USB. This can be avoided if park mode is enabled
in cases of only one endpoint is active.
3. But this delay is significant only with systems of large
latencies.
4. We have noticed that in cases where a device NAKs often, it
tends to bring down the performance for a single endpoint case.- Issue on "park mode"
1. LSP (List Processor) goes in and out of park mode irrespective
of the fact that there are more endpoints active. #LSP consider
that there is only one endpoint active.
2. This causes master scheduler and transaction handlers to think
that they are in park mode even though they are not. This is
because request to transaction handlers, generated by HSCH is
in park mode when the request is made
3. This causes a case where the master scheduler calculates wrongly
the number of TRB cache space available.
4. Because of the wrongly calculated number of TRB spaces, the core
fetches more TRBS than there is space for.
5. This causes overwriting the TRB cache area into the TRQ cache
area which is next to the TRB cache area.
6. This causes invalidating an entry in the TRQ
7. This causes transaction handlers to ignore a request in the TRQ
which it should have processed.
8. This causes the main scheduler to hang because it is waiting for
status from transaction handler.
9. This causes host controller to hang.- Work Around

Yet it is fairly common for various devices to use it, and a
popular proprietary operating system expects devices to provide
"OS descriptors", so Linux-based USB gadgets whishing to be able
to talk to a variety of operating systems should be able to provide
the "OS descriptors".This patch adds optional support for gadgets whishing to expose
the so called "OS Feature Descriptors", that is "Extended Compatibility ID"
and "Extended Properties".Hosts which do request "OS descriptors" from gadgets do so during
the enumeration phase and before the configuration is set with
SET_CONFIGURATION. What is more, those hosts never ask for configurations
at indices other than 0. Therefore, gadgets whishing to provide
"OS descriptors" must designate one configuration to be used with
this kind of hosts - this is what os_desc_config is added for in
struct usb_composite_dev. There is an additional advantage to it:
if a gadget provides "OS descriptors" and designates one configuration
to be used with such non-USB-compliant hosts it can invoke
"usb_add_config" in any order because the designated configuration
will be reported to be at index 0 anyway.This patch also adds handling vendor-specific requests addressed
at device or interface and related to handling "OS descriptors"."Signed-off-by: Li Jun
