usb: chipidea: Allow disabling streaming not only in udc mode

2013-01-12T00:01:07Z

When running a scp transfer using a USB/Ethernet adapter the following crash happens: $ scp test.tar.gz fabio@192.168.1.100:/home/fabio fabio@192.168.1.100's password: test.tar.gz 0% 0 0.0KB/s --:-- ETA ------------[ cut here ]------------ WARNING: at net/sched/sch_generic.c:255 dev_watchdog+0x2cc/0x2f0() NETDEV WATCHDOG: eth0 (asix): transmit queue 0 timed out Modules linked in: Backtrace: [<80011c94>] (dump_backtrace+0x0/0x10c) from [<804d3a5c>] (dump_stack+0x18/0x1c) r6:000000ff r5:80412388 r4:80685dc0 r3:80696cc0 [<804d3a44>] (dump_stack+0x0/0x1c) from [<80021868>] (warn_slowpath_common+0x54/0x6c) [<80021814>] (warn_slowpath_common+0x0/0x6c) from [<80021924>] (warn_slowpath_fmt+0x38/0x40) ... Setting SDIS (Stream Disable Mode- bit 4 of USBMODE register) fixes the problem. However, in current code CI13XXX_DISABLE_STREAMING flag is only set in udc mode, so allow disabling streaming also in host mode. Tested on a mx6qsabrelite board.

USB: chipidea: fix use after free bug

2012-11-26T22:59:00Z

The pointer to a platform_device struct must not be dereferenced after the device has been unregistered. This bug produces a crash when unloading the ci13xxx kernel module compiled with CONFIG_PAGE_POISONING enabled.

USB: EHCI: miscellaneous cleanups for the library conversion

2012-11-12T02:06:48Z

This patch (as1630) cleans up a few minor items resulting from the split-up of the ehci-hcd driver: Remove the product_desc string from the ehci_driver_overrides structure. All drivers will use the generic "EHCI Host Controller" string. (This was requested by Felipe Balbi.) Allow drivers to pass a NULL pointer to ehci_init_driver() if they don't have to override any settings. Remove a #define symbol that is no longer used from the ChipIdea host driver. Rename overrides to pci_overrides in ehci-pci.c, for consistency with ehci-platform.c. Mark the *_overrides structures as __initdata.

Merge tag 'gadget-for-v3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next

2012-11-12T01:31:53Z

USB gadget patches from Felipe: "usb: gadget: patches for v3.8 renesas_usbhs implements ->pullup() method, switches over to devm_request_irq(), adds support for DMA Engine and got a few miscelaneous cleanups. The NCM gadget got an endianness fix and the Ethernet gadget a frame size fix. We're finally removing the g_file_storage gadget and sticking to g_mass_storage and the new tcm_usb_gadget gadgets since that was a huge duplicaton of effort anyway. While removing g_file_storage, we also had to fix a bunch of defconfigs which were still pointing to the old gadget. There's a big series getting us closer to being able to introduce our configfs interface. The series converts functions into loadable modules which will, eventually, be registered to the configfs interface. Other than that there's the usual typo fixes and miscelaneous cleanups all over the place."

usb: gadget: Remove reference to is_dualspeed from sysfs.

2012-11-08T14:04:34Z

This commit removes the /sys/devices/platform//udc//is_dualspeed file and is_dualspeeed line from /sys/devices/platform/ci13xxx_*/udc/device file. The is_dualspeed file is superseded by maximum_speed in the same directory and is_dualspeed line in device file is superseded by max_speed line in the same file. The maximum_speed/max_speed specifies maximum speed supported by UDC. To check if dualspeeed is supported, check if the value is >= 3. Signed-off-by: Michal Nazarewicz Signed-off-by: Felipe Balbi

USB: EHCI: fix build error in ChipIdea host driver

2012-11-03T17:17:38Z

This patch (as1629) fixes a build error in the ChipIdea host driver when compiled for the ARM architecture. The error was introduced by commit 99f91934a907df31ba878dfdd090002049dc476a (USB: EHCI: make ehci-platform a separate driver). The fix is simple; an additional header-file #include is needed.
