While writel() takes the value and address arguments in that order, most
write functions (including in the regmap API) use the opposite
convention. Having the value first is considered confusing, and often
leads to more difficult to read code compared to the opposite convention
where the write call and the register name often fit on a single line:
rkisp1_write(rkisp1, RKISP1_CIF_THE_REG_NAME,
complicate_calculation + for / the_register
value + goes | here);
Swap the arguments of the rkisp1_write() function, and use the following
semantic patch to update the callers:
@@
expression rkisp1, value, address;
@@
- rkisp1_write(rkisp1, value, address)
+ rkisp1_write(rkisp1, address, value)
This commit also includes a few additional line break cleanups in the
rkisp1_write() calls, but no other manual change.

Set allow_cache_hints to 1 for the vb2_queue source and destination queues
in the mediatek vcodec V4L2 driver. This allows us to allocate buffers
with the V4L2_MEMORY_FLAG_NON_COHERENT set. On Mediatek SoCs, this enables
caching for this memory, which vastly improves performance when being read
from CPU. Read performance for these buffers is in turn important for
detiling MM21 video frames in userspace software, such as libyuv or
gstreamer.
This change should be safe from race conditions since videobuf2 already
invalidates or flushes the appropriate cache lines in its prepare() and
finish() methods.
Tested on a MT8183 SoC. Resulted in both correct detiling and a 10X
speedup.

This is a very old driver for very old hardware and it is one of
the very few remaining that does not use the vb2 framework (or
even the older videobuf framework), so deprecate this driver
and move it to staging with the intent to removing it altogether
by the end of 2022.
If someone wants to keep this driver, then it has to be converted
to use vb2.

This inserts 4 pixels of the RGB color 0xab55ab at the left hand side of
the image. This is only done for 3 or 4 byte RGB pixel formats. The HDMI
TMDS encoding of this pixel value equals the Video Guard Band value as
defined by HDMI (see section 5.2.2.1 in the HDMI 1.3 Specification) that
preceeds the first actual pixel of a video line. If an HDMI receiver
doesn't handle this correctly, then it might keep skipping these Video
Guard Band patterns and end up with a shorter video line. So this is a
nice pattern to test with.

To simplify the driver's maintenance it makes sense to escape from
hardcoded numbers of power domain resources per platform and statical
allocation of the resources. For instance on a QCOM SM8450 platform
the number of CAMSS power domains shall be bumped up to 6, also notably
CAMSS on MSM8916 has only one power domain, however it expects to get 2,
and thus it should result in a runtime error on driver probe.
The change fixes an issue mentioned above and gives more flexibility
to support more platforms in future.

Here is the "big" set of USB and Thunderbolt driver changes for
5.18-rc1. For the most part it's been a quiet development cycle for the
USB core, but there are the usual "hot spots" of development activity.
Included in here are:
- Thunderbolt driver updates:
- fixes for devices without displayport adapters
- lane bonding support and improvements
- other minor changes based on device testing
- dwc3 gadget driver changes. It seems this driver will never
be finished given that the IP core is showing up in zillions
of new devices and each implementation decides to do something
different with it...
- uvc gadget driver updates as more devices start to use and
rely on this hardware as well
- usb_maxpacket() api changes to remove an unneeded and unused
parameter.
- usb-serial driver device id updates and small cleanups
- typec cleanups and fixes based on device testing
- device tree updates for usb properties
- lots of other small fixes and driver updates.
All of these have been in linux-next for weeks with no reported

The process consist of alternating references parity, starting with
a reference of the same parity as the current picture. This
processs is done twice, once for short term references and a second
time for the long term references.

In the reference list builder, frame_num refers to FrameNumWrap

The same applies for long_term_pic_num and long_term_frame_idx.
Sort all type of references by frame_num so the sort can be reused
for fields reflist were the sorting is done using frame_num instead.
In short, pic_num is never actually used for building reference

The imx412/imx577 sensor has a reset line that is active low not active
high. Currently the logic for this is inverted.
The right way to define the reset line is to declare it active low in the
DTS and invert the logic currently contained in the driver.
The DTS should represent the hardware does i.e. reset is active low.
So:
+ reset-gpios = <&tlmm 78 GPIO_ACTIVE_LOW>;
not:
- reset-gpios = <&tlmm 78 GPIO_ACTIVE_HIGH>;
I was a bit reticent about changing this logic since I thought it might
negatively impact @intel.com users. Googling a bit though I believe this
sensor is used on "Keem Bay" which is clearly a DTS based system and is not
upstream yet.

If an adapter is trying to claim a free logical address then it is
in the 'is_configuring' state. If during that process the cable is
disconnected (HPD goes low, which in turn invalidates the physical
address), then cec_adap_unconfigure() is called, and that set the
is_configuring boolean to false, even though the thread that's
trying to claim an LA is still running.
Don't touch the is_configuring bool in cec_adap_unconfigure(), it
will eventually be cleared by the thread. By making that change
the cec_config_log_addr() function also had to change: it was
aborting if is_configuring became false (since that is what
cec_adap_unconfigure() did), but that no longer works. Instead
check if the physical address is invalid. That is a much
more appropriate check anyway.
This fixes a bug where the the adapter could be disabled even
though the device was still configuring. This could cause POLL
transmits to time out.

If, while trying to claim a free logical address, a POLL message
times out, then abort this process. A CEC_TX_STATUS_TIMEOUT
should be handled the same as a CEC_TX_STATUS_ABORTED.
This avoids a situation where transmits time out due to a
driver or hardware bug and it takes ages before the attempt
to find available free logical addresses finishes.

The __cec_s_log_addrs() function can configure or unconfigure the
adapter. The ioctl handler in cec-api.c will prevent it from being
called to configure the adapter if it was already configured (or in
the process of configuring). But it can still be called to unconfigure
an already unconfigured adapter, and it didn't check for that.
This can cause cec_activate_cnt_dec() to be called too often, causing
a WARN_ON.
Instead first check if adap->log_addrs.num_log_addrs == 0 and return
since in that case the adapter is already unconfigured.

It's OK to keep the pending pin events when disabling or
enabling the 'adapter'. Zeroing this can cause a race condition
if this happens when the pin kthread is handling a pin event
and calls atomic_dec later, causing work_pin_num_events to become
negative.
Just leave pending events in the queue, they'll be read eventually.

When the adap_enable callback is called the adap->lock is held.
When disabling the adapter it attempts to stop the kthread that
deals with receiving and transmitting messages. However, kthread_stop
waits for the thread to stop, so all that time adap->lock is held.
Unfortunately, the kernel thread itself can call functions that take
that same lock, so a deadlock can occur.
Change the logic to keep the kernel thread running and instead when
disabling the adapter, just set the pin to high, go to idle and then
to state OFF and disable the interrupt. Only stop the kernel thread
when the adapter is deleted.
This way disabling the adapter will not wait for anything and the
deadlock is avoided.

Since usb_register_dev() from imon_init_display() from imon_probe() holds
minor_rwsem while display_open() which holds driver_lock and ictx->lock is
called with minor_rwsem held from usb_open(), holding driver_lock or
ictx->lock when calling usb_register_dev() causes circular locking
dependency problem.
Since usb_deregister_dev() from imon_disconnect() holds minor_rwsem while
display_open() which holds driver_lock is called with minor_rwsem held,
holding driver_lock when calling usb_deregister_dev() also causes circular
locking dependency problem.
Sean Young explained that the problem is there are imon devices which have
two usb interfaces, even though it is one device. The probe and disconnect
function of both usb interfaces can run concurrently.
Alan Stern responded that the driver and USB cores guarantee that when an
interface is probed, both the interface and its USB device are locked.
Ditto for when the disconnect callback gets run. So concurrent probing/
disconnection of multiple interfaces on the same device is not possible.
Therefore, we don't need locks for handling race between imon_probe() and
imon_disconnect(). But we still need to handle race between display_open()
/vfd_write()/lcd_write()/display_close() and imon_disconnect(), for
disconnect event can happen while file descriptors are in use.
Since "struct file"->private_data is set by display_open(), vfd_write()/
lcd_write()/display_close() can assume that "struct file"->private_data
is not NULL even after usb_set_intfdata(interface, NULL) was called.
Replace insufficiently held driver_lock with refcount_t based management.
Add a boolean flag for recording whether imon_disconnect() was already
called. Use RCU for accessing this boolean flag and refcount_t.
Since the boolean flag for imon_disconnect() is shared, disconnect event
on either intf0 or intf1 affects both interfaces. But I assume that this
change does not matter, for usually disconnect event would not happen
while interfaces are in use.

The AWB workqueue runs in a kernel thread and needs to be synchronized
w.r.t. the streaming status.
It is possible that streaming is stopped while the AWB workq is running.
In this case it is likely that the check for vb2_start_streaming_called is
done at one point in time, but the AWB computations are done later,
including a call to isc_update_profile, which requires streaming to be
started.
Thus , isc_update_profile will fail if during this operation sequence the
streaming was stopped.
To solve this issue, a mutex is added, that will serialize the awb work and
streaming stopping, with the mention that either streaming is stopped
completely including termination of the last frame is done, and after that
the AWB work can check stream status and stop; either first AWB work is
completed and after that the streaming can stop correctly.
The awb spin lock cannot be used since this spinlock is taken in the same
context and using it in the stop streaming will result in a recursion BUG.

During experiments with libcamera, it looks like vb2_is_streaming returns
true before our start streaming is called.
Order of operations is streamon -> queue -> start_streaming
ISC would have started the DMA immediately when a buffer is being added
to the vbqueue if the queue is streaming.
It is more safe to start the DMA after the start streaming of the driver is
called.
Thus, even if vb2queue is streaming, add the buffer to the dma queue of the
driver instead of actually starting the DMA process, if the start streaming
has not been called yet.
Tho achieve this, we have to use vb2_start_streaming_called instead of
vb2_is_streaming.

Fix build errors when RADIO_TEA575X=y, VIDEO_BT848=m, and VIDEO_DEV=m.
The build errors occur due to [in drivers/media/Makefile]:
obj-$(CONFIG_VIDEO_DEV) += radio/
so the (would be) builtin tea575x.o is not being built.
This is also due to drivers/media/radio/Kconfig declaring a bool
Kconfig symbol (RADIO_ADAPTERS) that depends on a tristate (VIDEO_DEV),
so when VIDEO_DEV=m, RADIO_ADAPTERS becomes =y, and then the drivers
that depend on RADIO_ADPATERS can be configured as builtin (=y) or
as loadable modules (=m).
Fix this by converting RADIO_ADAPTERS to a tristate symbol instead
of a bool symbol.

The RDACM20 camera supports a single image format which is currently
listed as MEDIA_BUS_FMT_UYVY8_2X8. As the video stream is transmitted on
the GMSL serial bus, the 2X8 variant does not apply.
Fix the format by using MEDIA_BUS_FMT_UYVY8_1X16.
This fixes a runtime error which is now triggered as the MAX9286
deserializer implements .link_validate().

This patch aims to add UVC_GUID_FORMAT_H265
High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2.
They describe the same video encoding method.
So for handling their behavior is the same.
However, when external camera device describes this encoding method,
some use hevc, some use h265.
There is no uniform specification to describe this encoding method.
So if an external camera device use h265 to describe this encoding method,
driver will not recognize it.
Therefore, this patch is to enable driver to read HEVC/H265
and convert it to V4L2_PIX_FMT_HEVC.

The list iterator will point to a bogus position containing HEAD if
the list is empty or the element is not found in list. This case
should be checked before any use of the iterator, otherwise it will
lead to a invalid memory access. The missing check here is before
"pin = iterm->id;", just add check here to fix the security bug.
In addition, the list iterator value will *always* be set and non-NULL
by list_for_each_entry(), so it is incorrect to assume that the iterator
value will be NULL if the element is not found in list, considering
the (mis)use here: "if (iterm == NULL".
Use a new value 'it' as the list iterator, while use the old value
'iterm' as a dedicated pointer to point to the found element, which
1. can fix this bug, due to 'iterm' is NULL only if it's not found.
2. do not need to change all the uses of 'iterm' after the loop.
3. can also limit the scope of the list iterator 'it' *only inside*
the traversal loop by simply declaring 'it' inside the loop in the
future, as usage of the iterator outside of the list_for_each_entry
is considered harmful. https://lkml.org/lkml/2022/2/17/1032

so it can be shipped under Alpine which is musl-based, from Dominique Martinet.
8) Clean up {sk,task,inode} local storage trace RCU handling as they do not
need to use call_rcu_tasks_trace() barrier, from KP Singh.
9) Improve libbpf API documentation and fix error return handling of various
API functions, from Grant Seltzer.

The mipi_csis_dump_regs() function accesses the interface registers
in order to printout their values for debug purposes.
As the function access the registers, it requires the interface to be
powered up. Currently this is only enforced in one of the function's
callers (mipi_csis_log_status)() but not when the function is called by
the debugfs attribute handler.
Make sure to access registers only if the interface is powered up and

If the decoder prepare_run callback returns an error, the hardware
is never started and v4l2_m2m_job_finish() is called immediately,
currently in every error path.
Remove the duplicated job_finish calls from the error paths and reuse
the v4l2_m2m_job_finish() at the end of coda_pic_run_work instead.

Use v4l2_disable_ioctl() to disable the VIDIOC_TRY_ENCODER_CMD and
VIDIOC_ENCODER_CMD ioctls on decoder video devices and the
VIDIOC_TRY_DECODER_CMD and VIDIOC_DECODER_CMD ioctls on encoder
video devices.
This allows to drop the coda_try_encoder/decoder_cmd() functions
and to use v4l2_m2m_ioctl_try_encoder/decoder_cmd() directly.
