      usb: gadget: use $(srctree) instead of $(PWD) for includes · fa31409a

      Using $(PWD) breaks builds when make was invoked from outside
of the kernel tree.

      usb: gadget: udc: use USB API functions rather than constants · b8adc3d1
      Himangi Saraogi authored 
      This patch introduces the use of the functions usb_endpoint_type and
usb_endpoint_num.

The Coccinelle semantic patch that makes these changes is as follows:

@@ struct usb_endpoint_descriptor *epd; @@

- (epd->bEndpointAddress & \(USB_ENDPOINT_NUMBER_MASK\|0x0f\))
+ usb_endpoint_num(epd)

@@ struct usb_endpoint_descriptor *epd; @@

- (epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\))
+ usb_endpoint_type(epd)

      usbtest: Add interrupt EP testcases · 457a0955
      Amit Virdi authored 
      Two simple test cases for interrupt endpoints are added to the usbtest.c file.
These are simple non-queued interrupt IN and interrupt OUT transfers. Currently,
only gadget zero is capable of executing the interrupt EP test cases. However,
extending the same to other gadgets is extremely simple and can be done
on-demand.

The two new tests added are
  - Test 25: To verify Interrupt OUT transfer
  - Test 26: To verify Interrupt IN transfer

Since the default value of wMaxPacketSize is set as 1024, so interrupt
IN transfers must be specified with the size parameter = multiple of
1024. Otherwise the default value (512) in the usbtest application fails
the transfer. See [RUN 4] for sample logs

The application logs (usbtest) and corresponding kernel logs are as
following:

[Run 1]
./testusb -a -c 10 -s 2048 -t 26 -v 511
usbtest 7-1:3.0: TEST 26: read 2048 bytes 10 times

[Run 2]
./testusb -a -c 10 -s 1024 -t 25 -v 511
usbtest 7-1:3.0: TEST 25: write 1024 bytes 10 times

[Run 3]
./testusb -a -c 10 -s 1098 -t 25 -v 511
usbtest 7-1:3.0: TEST 25: write 1098 bytes 10 times

[Run 4 - Failure case scenario]
./testusb -a  -t 26
unknown speed   /dev/bus/usb/007/004    0
/dev/bus/usb/007/004 test 26 --> 75 (Value too large for defined data type)

usbtest 7-1:3.0: TEST 26: read 512 bytes 1000 times
usb 7-1: test26 failed, iterations left 999, status -75 (not 0)

      usb: gadget: zero: Add support for interrupt EP · ef11982d
      Amit Virdi authored 
      Interrupt endpoints behave quite similar to the bulk endpoints with the
difference that the endpoints expect data sending/reception request at
particular intervals till the whole data has not been transmitted.

The interrupt EP support is added to gadget zero. A new alternate setting (=2)
has been added. It has 2 interrupt endpoints. The default parameters are set as:
	bInterval: 1 ms for FS and 8 uFrames (implying 1 ms) for HS/SS
	wMaxPacketSize: 64 bytes for FS and 1024 bytes for HS/SS
However, the same can be overridden through the module parameter interface.

The code is tested for HS and SS on a platform having DWC3 controller.

      usb: gadget: serial: remove PREFIX macro · c572a217
      Richard Leitner authored 
      Remove the ttyGS PREFIX macro from u_serial.c and replace all occurences with
the hardcoded ttyGS string.

This macro was mostly used in a few debug/warning messages and a lot of
hardcoded ttyGS existed beneath. It may have been used for renaming the
tty, but if done so most debug messages would have ignored this.

Due to the fact the usage of this PREFIX in all debug calls would have
resulted in a hard to read/grep code it is removed completely.

      usb: phy: msm: Make phy_reset clk and reset line optional. · a1a4caf4
      Srinivas Kandagatla authored 
      This patch makes the phy reset clk and reset line optional as this clk
is not available on boards like IFC6410 with APQ8064.

phy-reset clk is only used as argument to the mach level callbacks, so
this patch adds condition before clk_get calls so that the driver
wouldn't fail on SOCs which do not have this support.

      usb: phy: mxs: Add VF610 USB PHY support · d0ee68b5
      Stefan Agner authored 
      This adds support for the USB PHY in Vybrid VF610. We assume that
the disconnection without VBUS is also needed for Vybrid.

Tests showed, without MXS_PHY_NEED_IP_FIX, enumeration of devices
behind a USB Hub fails with errors:

[  215.163507] usb usb1-port1: cannot reset (err = -32)
[  215.170498] usb usb1-port1: cannot reset (err = -32)
[  215.185120] usb usb1-port1: cannot reset (err = -32)
[  215.191345] usb usb1-port1: cannot reset (err = -32)
[  215.202487] usb usb1-port1: cannot reset (err = -32)
[  215.207718] usb usb1-port1: Cannot enable. Maybe the USB cable is bad?
[  215.219317] usb usb1-port1: unable to enumerate USB device

Hence we also enable the MXS_PHY_NEED_IP_FIX flag.
