- fix a regression at the CEC adapter core
- two uAPI patches (one revert) for changes in this development cycle
* tag 'media/v5.9-3' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media:
media: dt-bindings: media: imx274: Convert to json-schema
media: media/v4l2: remove V4L2_FLAG_MEMORY_NON_CONSISTENT flag
media: cec-adap.c: don't use flush_scheduled_work()
The patch partially reverts some of the UAPI bits of the buffer
cache management hints. Namely, the queue consistency (memory
coherency) user-space hint because, as it turned out, the kernel
implementation of this feature was misusing DMA_ATTR_NON_CONSISTENT.
The patch reverts both kernel and user space parts: removes the
DMA consistency attr functions, rolls back changes to v4l2_requestbuffers,
v4l2_create_buffers structures and corresponding UAPI functions
(plus compat32 layer) and cleans up the documentation.

For some inexplicable reason I decided to call flush_scheduled_work()
instead of cancel_delayed_work_sync(). The problem with that is that
flush_scheduled_work() waits for *all* queued scheduled work to be
completed instead of just the work itself.
This can cause a deadlock if a CEC driver also schedules work that
takes the same lock. See the comments for flush_scheduled_work() in
linux/workqueue.h.
This is exactly what has been observed a few times.
This patch simply replaces flush_scheduled_work() by
cancel_delayed_work_sync().

During bit-banging the IR on a gpio pin, we cannot be scheduled or have
anything interrupt us, else the generated signal will be incorrect.
Therefore, we need to disable interrupts on the local cpu. This also
disables preemption.
local_irq_disable() does exactly what we need and does not require a

After the recent conversion of the media build infrastructure to select
V4L2 components instead of depending on their presence, which took place
in:
32a363d0b0 ("media: Kconfig files: use select for V4L2 subdevs and MC")
imx214 stands out as being the (only?) media I2C driver that still depends
on a V4L2 core symbol instead of selecting it.
This confuses the build system which claims it has detected a circular
dependency when other drivers select the same symbol as the imx214
driver does.
drivers/media/i2c/Kconfig:728:error: recursive dependency detected!
drivers/media/i2c/Kconfig:728: symbol VIDEO_IMX214 depends on V4L2_FWNODE
drivers/media/v4l2-core/Kconfig:71: symbol V4L2_FWNODE is selected by VIDEO_BCM2835_UNICAM

drivers/media/v4l2-core/Kconfig:19: symbol VIDEO_V4L2_SUBDEV_API depends on MEDIA_CONTROLLER
drivers/media/Kconfig:168: symbol MEDIA_CONTROLLER is selected by VIDEO_IMX214
Fix this by making the imx214 driver select V4L2_FWNODE instead of
depending on it and align it with all the other drivers.

When compiled on 32-bit ARM, the CAL driver fails with the FIELD_PREP()

the inline cal_write_field() function pass a constant mask, the mask
parameter itself is a variable, which likely doesn't please the

"This adds the sched_set_fifo*() encapsulation APIs to remove static
priority level knowledge from non-scheduler code.
The three APIs for non-scheduler code to set SCHED_FIFO are:

- sched_set_fifo_low()
- sched_set_normal()
These are two FIFO priority levels: default (high), and a 'low'
priority level, plus sched_set_normal() to set the policy back to
non-SCHED_FIFO.
Since the changes affect a lot of non-scheduler code, we kept this in
a separate tree"

Drivers using legacy PM have to manage PCI states and device's PM states
themselves. They also need to take care of configuration registers.
With improved and powerful support of generic PM, PCI Core takes care of
above mentioned, device-independent, jobs.
This driver makes use of PCI helper functions like
pci_save/restore_state() and pci_enable/disable_device() to do required
operations. In generic mode, they are no longer needed.
Change function parameter in both .suspend() and .resume() to
"struct device*" type.

fwnode matching was designed to match on nodes corresponding to a
device. Some drivers, however, needed to match on endpoints, and have
passed endpoint fwnodes to v4l2-async. This works when both the subdev
and the notifier use the same fwnode types (endpoint or device), but
makes drivers that use different types incompatible.
Fix this by extending the fwnode match to handle fwnodes of different
types. When the types (deduced from the presence of remote endpoints)
are different, retrieve the device fwnode for the side that provides an
endpoint fwnode, and compare it with the device fwnode provided by the
other side. This allows interoperability between all drivers, regardless
of which type of fwnode they use for matching.
