2014-08-29usbtest: Add interrupt EP testcasesAmit Virdi1-15/+98
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) Signed-off-by: Amit Virdi <amit.virdi@st.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2014-08-27f_ncm: Don't use netdev_start_xmit().David S. Miller1-1/+9
Unfortunately, the USB gadget layer has this weird things where NULL skbs are passed into ops->ndo_start_xmit() in order to trigger the dev->wrap() calls to build packets. This is completely outside of the allowable range of sane arguments for the ndo_start_xmit method. All invocations of ndo_start_xmit() should be with non-NULL SKB arguments. Put back the direct call, but with a comment explaining how this is not acceptable in the long term. Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S.

2014-08-27usb: gadget: zero: Add support for interrupt EPAmit Virdi4-22/+526
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.

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.

Since we want to keep support for both older usb-phys as well as the newer generic phys, lets first get the generic PHYs and fallback to older USB-PHYs only when we fail to get the former. This should fix the issue with ehci-exynos and ohci-exynos, wherein in the absence of SAMSUNG_USB2PHY config symbol, we end up getting the NOP_USB_XCEIV phy when the same is enabled.

Converting uac2 to the new function interface requires converting the USB uac2's function code and its users. This patch converts the f_uac2.c to the new function interface. The file is now compiled into a separate usb_f_uac2.ko module. The old function interface is provided by means of a preprocessor conditional directives. After all users are converted, the old interface can be removed.

2014-08-20usb: gadget: audio: Use container_of to free audio_devAndrzej Pietrasiewicz2-24/+14
Eliminate static struct *agdev_g from f_uac2.c. It is used for freeing its memory, but the same address can be found by calling container_of in afunc_unbind(). This implies eliminating uac2_unbind_config(). The audio_config_driver in audio.c does not have its unbind method any more. It has been used only when uac2 is used, so uac2 itself can handle unbinding in afunc_unbind().
