If ffs-test is used with a kernel prior to 3.14, which do not support the new descriptors format, it will fail when trying to write the descriptors. Add a function that converts the new descriptors to the legacy ones and use it to retry writing the descriptors using the legacy format. Also add “-l” flag to ffs-test which will cause the tool to never try the new format and instead immediatelly try the legacy one. This should be useful to test whether parsing of the old format still works on given 3.14+ kernel. Signed-off-by:

Since commit [ac8dde11: “Add flags to descriptors block”] functionfs supports a new, more powerful and extensible, descriptor format. Since ffs-test is probably the first thing users of the functionfs interface see when they start writing functionfs user space daemons, convert it to use the new format thus promoting it.

The structure can be used with user space tools that use the new functionfs description format, for example as follows: static const struct { struct usb_functionfs_descs_head_v2 header; __le32 fs_count; __le32 hs_count; struct { … } fs_desc; struct { … } hs_desc; } descriptors = { .header = { .magic = cpu_to_le32(FUNCTIONFS_DESCRIPTORS_MAGIC_V2), .length = cpu_to_le32(sizeof(descriptors)), .flags = cpu_to_le32(FUNCTIONFS_HAS_FS_DESC | FUNCTIONFS_HAS_HS_DESC) }, .fs_count = cpu_to_le32(X), .fs_desc = { … }, .hs_count = cpu_to_le32(Y), .hs_desc = { … } }; Signed-off-by: -

commit f2267089(usb: gadget: composite: dequeue cdev->req before free it in composite_dev_cleanup) fixed a bug: free the usb request(i.e. cdev->req) but does not dequeue it beforehand. This fix is not proper enough because it dequeues the request after free its data buffer, considering the hardware can access the buffer's memory anytime before the request's complettion rountine runs, and usb_ep_dequeue always call the complettion rountine before it returns, so the best way is to dequeue the request before free its buffer.

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:

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. Signed-off-by:

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. Signed-off-by:

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.

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. Acked-by:

The file is now compiled into a separate usb_f_uac1.ko module. The old function interface is provided by means of a preprocessor conditional directives.

Integrating configfs requires converting f_uac1 to new function interface, which in turn requires converting it to the new function interface, which involves separate compilation of f_uac1.c into usb_f_uac1.ko. u_uac1.c contains some module parameters. After this patch is applied they are still a part of the resulting g_audio.ko, but can be guarded with a compatiblity flag which will be removed when no users of the old function interface of f_uac1 are left.

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(). Tested-by:
