usb: dwc2: Fix disable all EP's on disconnect
commit
4fe4f9fecc36956fd53c8edf96dd0c691ef98ff9 upstream.
Disabling all EP's allow to reset EP's to initial state.
Introduced new function dwc2_hsotg_ep_disable_lock() which
before calling dwc2_hsotg_ep_disable() function acquire
hsotg->lock and release on exiting.
From dwc2_hsotg_ep_disable() function removed acquiring
hsotg->lock.
In dwc2_hsotg_core_init_disconnected() function when USB
reset interrupt asserted disabling all ep’s by
dwc2_hsotg_ep_disable() function.
This updates eliminating sparse imbalance warnings.
Reverted changes in dwc2_hostg_disconnect() function.
Introduced new function dwc2_hsotg_ep_disable_lock().
Changed dwc2_hsotg_ep_ops. Now disable point to
dwc2_hsotg_ep_disable_lock() function.
In functions dwc2_hsotg_udc_stop() and dwc2_hsotg_suspend()
dwc2_hsotg_ep_disable() function replaced by
dwc2_hsotg_ep_disable_lock() function.
In dwc2_hsotg_ep_disable() function removed acquiring

pwm: Send a uevent on the pwmchip device upon channel sysfs (un)export

This patch sends a uevent (KOBJ_CHANGE) on the pwmchipN device,
everytime a pwmX channel has been exported/unexported via sysfs. This
allows udev to implement rules on such events, like:
SUBSYSTEM=="pwm*", PROGRAM="/bin/sh -c '\

This is a replacement patch for commit

This reverts commit
7e5d1fd75c3dde9fc10c4472b9368089d1b81d00 ("pwm: Set
class for exported channels in sysfs") as it causes regression with
multiple pwm chip[1], when exporting a pwm channel (echo X > export):
- ABI (Documentation/ABI/testing/sysfs-class-pwm) states pwmX should be
created in /sys/class/pwm/pwmchipN/pwmX
- Reverted patch causes new entry to be also created directly in
/sys/class/pwm/pwmX
- 1st time, exporting pwmX will create an entry in /sys/class/pwm/pwmX
- class attributes are added under pwmX folder, such as export, unexport
npwm, symlinks. This is wrong as it belongs to pwmchipN. It may cause
bad behavior and report wrong values.
- when another export happens on another pwmchip, it can't be created
(e.g. -EEXIST). This is causing the issue with multiple pwmchip.
Example on stm32 (stm32429i-eval) platform:
$ ls /sys/class/pwm
pwmchip0 pwmchip4
$ cd /sys/class/pwm/pwmchip0/
$ echo 0 > export
$ ls /sys/class/pwm

$ cd /sys/class/pwm/pwmchip4/
$ echo 0 > export

The SC16IS752 has an Enhanced Feature Register which is aliased at the

Register. If an interrupt is raised while the EFR is mapped in then
the ISR won't be able to access the IIR, leading to the "Unexpected

Avoid the problem by claiming a mutex around accesses to the EFR
register, also claiming the mutex in the interrupt handler work
item (this is equivalent to disabling interrupts to interlock against
a non-threaded interrupt handler).

gpio-ir: change default pull configuration to up
IR receivers like the TSOP series from Vishay and compatible ones
have active-low open collector outputs with an internal pull up of
about 30k (according to the TSOP datasheets).
Activating a pull-down resistor on the GPIO will make it work against
the pull-up in the IR receiver and brings the idle input voltage down
to about 1.9V (measured on a RPi3B+ with a TSOP4438). While that's
usually enough to make the RPi see a high signal it's certainly not
optimal and may even fail when using an IR receiver with a weaker pull-up.
Switching the default GPIO pull to "up" results in an input voltage
level of about 3.3V and ensures that an idle state (high signal) will
be detected if no IR receiver is attached.

Especially on platforms without any boot firmware integration of the TPM
(e.g. raspberry pi) it does not add any value for the tpm subsystem,

media: vb2: Allow reqbufs(0) with "in use" MMAP buffers
Videobuf2 presently does not allow VIDIOC_REQBUFS to destroy outstanding
buffers if the queue is of type V4L2_MEMORY_MMAP, and if the buffers are
considered "in use". This is different behavior than for other memory
types and prevents us from deallocating buffers in following two cases:
1) There are outstanding mmap()ed views on the buffer. However even if
we put the buffer in reqbufs(0), there will be remaining references,
due to vma .open/close() adjusting vb2 buffer refcount appropriately.
This means that the buffer will be in fact freed only when the last
mmap()ed view is unmapped.
2) Buffer has been exported as a DMABUF. Refcount of the vb2 buffer
is managed properly by VB2 DMABUF ops, i.e. incremented on DMABUF
get and decremented on DMABUF release. This means that the buffer
will be alive until all importers release it.
Considering both cases above, there does not seem to be any need to
prevent reqbufs(0) operation, because buffer lifetime is already
properly managed by both mmap() and DMABUF code paths. Let's remove it
and allow userspace freeing the queue (and potentially allocating a new
one) even though old buffers might be still in processing.

There is an awkward situation with H264 header bytes. Currently

returning the timestamp of the last buffer to have been received,
