Added the Test device VID/PID in TPL list for OTG 2.0
Removed the is_host_active check while setting the test mode.
OTG Test Mode support is added.An OTG device shall support the
test device that initiates these test modes. Upon enumeration
by the host, the test device presents a VID/PID pair that
defines a test mode or operation to execute. Upon enumerating
the test device with VID of 0x1A0A, the Targeted Host shall
perform the following operations based on the PID presented.
PID Test Mode

usb: fixes for v3.4-rc cycle
A few more fixes for v3.4-rc cycle.
It includes a couple of fixes to the ordering of the methods in udc-core.c.
Without these two patches, we will have issues when either unregistering a
gadget driver (triggered with dummy_hcd only) or issuing a device-initiated
disconnect through sysfs.
There's also a fix on dummy_hcd to not call ->pullup() from udc_stop() because
udc-core.c already handles that.
A fix to MUSB as promised, to kill the compile warnings regarding deprecated
interfaces. We are essentially dropping the __deprecated flag because it
doesn't look like we will ever be able to live without it when we consider the
amount of silicon issues we find on different MUSB instantiations.
A couple of other fixes are also available, one adding the missing transceiver
events to gpio_vbus and another adding a missing unregister call to MUSB's
davinci glue layer.
|
|
This patch (as1548) fixes a recently-introduced incompatibility
between the UDC core and the dummy-hcd driver. Commit
8ae8090c82eb407267001f75b3d256b3bd4ae691 (usb: gadget: udc-core: fix
asymmetric calls in remove_driver) moved the usb_gadget_udc_stop()
call in usb_gadget_remove_driver() below the usb_gadget_disconnect()
call.
As a result, usb_gadget_disconnect() gets called at a time when the
gadget driver believes it has been unbound but dummy-hcd believes
it has not. A nasty error ensues when dummy-hcd calls the gadget
driver's disconnect method a second time.
To fix the problem, this patch moves the gadget driver's unbind
notification after the usb_gadget_disconnect() call. Now nothing
happens between the two unbind notifications, so nothing goes wrong.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus
usb: fixes for v3.4-rc cycle
Here are the fixes I have queued for v3.4-rc cycle so far.
It includes fixes on many of the gadget drivers and a few
of the UDC controller drivers.
For musb we have a fix for a kernel oops when unloading
omap2430.ko glue layer, proper error checking for pm_runtime_*,
fix for the ULPI transfer block, and a bug fix in musb_cleanup_urb
routine.
For s3c-hsotg we have mostly FIFO-related fixes (proper TX FIFO
allocation, TX FIFO corruption fix in DMA mode) but also a couple
of minor fixes (fixing maximum packet size for ep0 and fix for
big transfers with DMA).
For the dwc3 driver we have a memory leak fix, a very important
fix for USB30CV with SetFeature tests and the hability to handle
ep0 requests bigger than wMaxPacketSize.
On top of that there's a bunch of gadget driver minor fixes adding
proper section annotations, and fixing up the sysfs interface for
doing device-initiated connect/disconnect and so on.
All patches have been pending on the mailing list for quite a while
and look good for your for-linus branch.

This patch (as1539) fixes a minor bug in the mass-storage gadget
drivers. When an unknown command is received, the error code sent
back is "Invalid Field in CDB" rather than "Invalid Command". This is
because the bitmask of CDB bytes allowed to be nonzero is incorrect.
When handling an unknown command, we don't care which command bytes
are nonzero. All the bits in the mask should be set, not just eight
of them.

usb: gadget: eliminate NULL pointer dereference (bugfix)
This patch fixes a bug which causes NULL pointer dereference in
ffs_ep0_ioctl. The bug happens when the FunctionFS is not bound (either
has not been bound yet or has been bound and then unbound) and can be
reproduced with running the following commands:
$ insmod g_ffs.ko
$ mount -t functionfs func /dev/usbgadget
$ ./null
where null.c is:
#include <fcntl.h>
#include <linux/usb/functionfs.h>
int main(void)
{
int fd = open("/dev/usbgadget/ep0", O_RDWR);
ioctl(fd, FUNCTIONFS_CLEAR_HALT);

routine
This patch removes the non-required spinlock acquire/release calls on
'queue->irqlock' from 'uvc_queue_next_buffer' routine.
This routine is called from 'video->encode' function (which translates to
either 'uvc_video_encode_bulk' or 'uvc_video_encode_isoc') in 'uvc_video.c'.
As, the 'video->encode' routines are called with 'queue->irqlock' already held,
so acquiring a 'queue->irqlock' again in 'uvc_queue_next_buffer' routine causes
a spin lock recursion.

During modprobe of gadget driver, pullup is called after
udc_start. In order to make the exit path symmetric when
removing a gadget driver, call pullup before ->udc_stop.
This is needed to avoid issues with PM where udc_stop
disables the module completely (put IP in reset state,
cut functional and interface clocks, and so on), which
prevents us from accessing the IP's address space,
thus creating the possibility of an abort exception
when we try to access IP's address space after clocks
are off.

- For Control Read transfer, the ACK handshake on an IN transaction
may be corrupted, so the device may not receive the ACK for data
stage, the complete irq will not occur at this situation.
Therefore, we need to move prime status stage from complete irq
routine to the place where the data stage has just primed, or the
host will never get ACK for status stage.
The above issue has been described at USB2.0 spec chapter 8.5.3.3.
- After adding prime status stage just after prime the data stage,
there is a potential problem when the status dTD is added before the data stage
has primed by hardware. The reason is the device's dTD descriptor has NO direction bit,
if data stage (IN) prime hasn't finished, the status stage(OUT)
dTD will be added at data stage dTD's Next dTD Pointer, so when the data stage
transfer has finished, the status dTD will be primed as IN by hardware,
then the host will never receive ACK from the device side for status stage.
- Delete below code at fsl_ep_queue:
/* Update ep0 state */
if ((ep_index(ep) == 0))
udc->ep0_state = DATA_STATE_XMIT;
the udc->ep0_state will be updated again after udc->driver->setup
finishes.
It is tested at i.mx51 bbg board with g_mass_storage, g_ether, g_serial.

When we want to do device-initiated disconnect,
let's make sure we stop the UDC in order to
e.g. allow lower power states to be achieved by
turning off unnecessary clocks and/or stoping
PHYs.
When reconnecting, call ->udc_start() again to
make sure UDC is reinitialized.

When adb is enabled, only connect the gadget when adbd is ready. If adbd
dies or is restarted (e.g. "adb root"), the gadget is disconnected when
the adb device is close, and it is re-connected once adb re-open the
device.
- Add callbacks to adb, similar to FunctionFs callbacks, to notify the
gadget when the daemon is ready or closed.
- Refcount calls to android_enable/android_disable to enable the gadget
only once all the function daemons are ready.
- Add enable/disble to android_usb_function to notify the function when
it is added/removed from the list of enabled functions.

USB accessory mode allows users to connect USB host hardware
specifically designed for Android-powered devices. The accessories
must adhere to the Android accessory protocol outlined in the
http://accessories.android.com documentation. This allows
Android devices that cannot act as a USB host to still interact with
USB hardware. When an Android device is in USB accessory mode, the
attached Android USB accessory acts as the host, provides power
to the USB bus, and enumerates connected devices.

The Android Gadget driver is a composite driver that allows
userspace to change at runtime the list of functions enabled in
its configuration and to configure these functions. It supports
multiple functions: acm, adb, rndis, mtp/ptp, mass storage and
accessory.
It is usually controlled by a daemon that changes the configuration
based on user settings. For example, rndis is enabled when the user
enables sharing the phone data connection and adb (Android Debug
Bridge) is only enabled when the user wants to debug applications
for security reasons.
As an example on how to use it, the following shell commands will
make the gadget disconnect from the host and make it be re-enumerated
as a composite with 1 rndis and 2 acm interfaces, and a different
product id:
echo 0 > /sys/class/android_usb/android0/enable
echo rndis,acm > /sys/class/android_usb/android0/functions
echo 2 > /sys/class/android_usb/android0/f_acm/instances
echo 2d01 > /sys/class/android_usb/android0/idProduct
echo 1 > /sys/class/android_usb/android0/enable
The driver requires a gadget controller that supports software
control of the D+ pullup and the controller driver must support
disabling the pullup during composite_bind.

Pull "Disintegrate and delete asm/system.h" from David Howells:
"Here are a bunch of patches to disintegrate asm/system.h into a set of
separate bits to relieve the problem of circular inclusion
dependencies.
I've built all the working defconfigs from all the arches that I can
and made sure that they don't break.
The reason for these patches is that I recently encountered a circular
dependency problem that came about when I produced some patches to
optimise get_order() by rewriting it to use ilog2().
This uses bitops - and on the SH arch asm/bitops.h drags in
asm-generic/get_order.h by a circuituous route involving asm/system.h.
The main difficulty seems to be asm/system.h. It holds a number of
low level bits with no/few dependencies that are commonly used (eg.
memory barriers) and a number of bits with more dependencies that
aren't used in many places (eg. switch_to()).
These patches break asm/system.h up into the following core pieces:
(1) asm/barrier.h
Move memory barriers here. This already done for MIPS and Alpha.
(2) asm/switch_to.h
Move switch_to() and related stuff here.
(3) asm/exec.h
Move arch_align_stack() here. Other process execution related bits
could perhaps go here from asm/processor.h.
(4) asm/cmpxchg.h
Move xchg() and cmpxchg() here as they're full word atomic ops and
frequently used by atomic_xchg() and atomic_cmpxchg().
(5) asm/bug.h
Move die() and related bits.
(6) asm/auxvec.h
Move AT_VECTOR_SIZE_ARCH here.
Other arch headers are created as needed on a per-arch basis."
Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that. We'll find out anything that got broken and fix it..

Pull "ARM: More device tree support updates" from Olof Johansson:
"This branch contains a number of updates for device tree support on
several ARM platforms, in particular:
* AT91 continues the device tree conversion adding support for a
number of on-chip drivers and other functionality
* ux500 adds probing of some of the core SoC blocks through device
tree
* Initial device tree support for ST SPEAr600 platforms
* kirkwood continues the conversion to device-tree probing"
Manually merge arch/arm/mach-ux500/Kconfig due to MACH_U8500 rename, and
drivers/usb/gadget/at91_udc.c due to header file include cleanups.
Also do an "evil merge" for the MACH_U8500 config option rename that the
affected RMI4 touchscreen driver in staging. It's called MACH_MOP500
now, and it was missed during previous merges.

Now skb_add_rx_frag() has a truesize parameter, we can fix f_phonet to
properly account truesize of each fragment : a full page.
