Ido Shayevitz fc065a0952 usb: gadget: fsl_qe_udc: Remove unneeded condition
The removed condition is always true, since the endpoint descriptor is
set prior to calling the enable endpoint.

Sebastian Andrzej Siewior 504d14c465 usb: gadget: fsl_qe_udc: remove not implemented callbacks
All of this callbacks which I remove here are not implemented and return
an error code. The gadget code returns an error code if a callback is
missing so there is no need to implement this twice.

Michal Nazarewicz 7177aed44f usb: gadget: rename usb_gadget_driver::speed to max_speed
This commit renames the “speed” field of the usb_gadget_driver
structure to “max_speed”.  This is so that to make it more
apparent that the field represents the maximum speed gadget
driver can support.

This also make the field look more like fields with the same
name in usb_gadget and usb_composite_driver structures.  All
of those represent the *maximal* speed given entity supports.

After this commit, there are the following fields in various
structures:
* usb_gadget::speed - the current connection speed,
* usb_gadget::max_speed - maximal speed UDC supports,
* usb_gadget_driver::max_speed - maximal speed gadget driver
  supports, and
* usb_composite_driver::max_speed - maximal speed composite
  gadget supports.

Michal Nazarewicz bfe0658b40 usb: udc: Fix gadget driver's speed check in various UDC drivers
Several UDC drivers had a gadget driver's speed sanity check of the
form of:

	driver->speed != USB_SPEED_HIGH

or:

	driver->speed != USB_SPEED_HIGH && driver->speed != USB_SPEED_FULL

As more and more gadget drivers support USB SuperSpeed, driver->speed
may be set to USB_SPEED_SUPER and UDC driver should handle such gadget
correctly.  The above checks however fail to recognise USB_SPEED_SUPER
as a valid speed.

This commit changes the two checks to:

	driver->speed < USB_SPEED_HIGH

or:

	driver->speed < USB_SPEED_FULL

respectively.

Grant Likely b1608d69cb drivercore: revert addition of of_match to struct device
Commit b826291c, "drivercore/dt: add a match table pointer to struct
device" added an of_match pointer to struct device to cache the
of_match_table entry discovered at driver match time.  This was unsafe
because matching is not an atomic operation with probing a driver.  If
two or more drivers are attempted to be matched to a driver at the
same time, then the cached matching entry pointer could get
overwritten.

This patch reverts the of_match cache pointer and reworks all users to
call of_match_device() directly instead.

Valentin Longchamp d834508e15 USB: fsl_qe_udc: send ZLP when zero flag and length % maxpacket == 0
The driver did not take the zero flag in the USB request. If the
request length is the same as the endpoint's maxpacket, an additional
ZLP with no data has to be transmitted.

The method used here is inspired to what is done in fsl_udc_core.c
(and pxa27x_udc.c and at91_udc.c) where this is supported.

There already was a discussion about this topic with people from
Keymile, and I propose here a better implementation:

will be trivial.  This patch looks big and scary because it touches so

early.

Li Yang 928dfa6c62 usb/fsl_qe_udc: fix response to get status request
The original code didn't respond correctly to get status request on
device and endpoint.  Although normal operations can work without the
fix.  It is not compliant with USB spec chapter9 and fails USBCV ch9
tests.  The patch fix this and a few style/typo problems.

Li Yang 3948f0e0c9 usb: add Freescale QE/CPM USB peripheral controller driver
Some of Freescale SoC chips have a QE or CPM co-processor which
supports full speed USB.  The driver adds device mode support
of both QE and CPM USB controller to Linux USB gadget.  The
driver is tested with MPC8360 and MPC8272, and should work with
other models having QE/CPM given minor tweaks.
