Similar to other drivers, this should fix a Clang compilar warning when
building without CONFIG_OF in which case of_match_ptr() is NULL and
the const struct we would use otherwise is unused.

Commit a4b83deb3e ("media: videobuf2: rework vb2_mem_ops API")
added a new vb member to struct vb2_dma_sg_buf, but it only added
code setting this to the vb2_dma_sg_alloc() function and not to the
vb2_dma_sg_get_userptr() and vb2_dma_sg_attach_dmabuf() which also
create vb2_dma_sg_buf objects.
This is causing a crash due to a NULL pointer deref when using
libcamera on devices with an Intel IPU3 (qcam app).
Fix these crashes by assigning buf->vb in the other 2 functions too,
note libcamera tests the vb2_dma_sg_get_userptr() path, the change
to the vb2_dma_sg_attach_dmabuf() path is untested.

My previous bugfix addressed an API inconsistency found by syzbot,
and it correctly fixed the issue on x86-64 machines, which now behave
correctly for both native and compat tasks.
Unfortunately, John found that the patch broke compat mode on all other
architectures, as they can no longer rely on the VIDIOC_DQEVENT_TIME32
code from the native handler as a fallback in the compat code.
The best way I can see for addressing this is to generalize the
VIDIOC_DQEVENT32_TIME32 code from x86 and use that for all architectures,
leaving only the VIDIOC_DQEVENT32 variant as x86 specific. The original
code was trying to be clever and use the same conversion helper for native
32-bit code and compat mode, but that turned out to be too obscure so
even I missed that bit I had introduced myself when I made the fix.

reviewed and acked by the dma_buf maintainers
- iio driver update (going through this tree not staging as they
really do not belong going through that tree anymore)
- counter driver updates
- hwmon driver updates that the counter drivers needed, acked by
the hwmon maintainer
- xillybus driver updates
- binder driver updates
- extcon driver updates
- dma_buf module namespaces added (will cause a build error in

the drm tree)
- lkdtm driver updates

In order to better track where in the kernel the dma-buf code is used,
put the symbols in the namespace DMA_BUF and modify all users of the
symbols to properly import the namespace to not break the build at the
same time.
Now the output of modinfo shows the use of these symbols, making it
easier to watch for users over time:

In existing implementation, driver is freeing and un-mapping all the
decoded picture buffers(DPB) as part of dynamic resolution change(DRC)
handling. As a result, when firmware try to access the DPB buffer, from
previous sequence, SMMU context fault is seen due to the buffer being
already unmapped.
With this change, driver defines ownership of each DPB buffer. If a buffer
is owned by firmware, driver would skip from un-mapping the same.

According to stateful decoder docs a fatal failure of decoding
(and encoding) could be recover it by closing the corresponding
file handle and open new one or reinitialize decoding (and encoding)
by stop streaming on both queues. In order to satisfy this
requirement we add a mechanism ins sys_error_handler and
corresponding decoder and encoder drivers to wait for sys_error_done

Currently, the driver always writes PAL as video format into the SPS of
the encoded stream.
Set the video format to the default value 5 (unspecified) and use the
color description that is already configured on the channel as color
space. This fixes the color space definition in the coded data to
reflect the configured color space of the video data that is encoded.
Add lookup functions to convert the color primaries, transfer function
and matrix coefficients from the V4L2 control values to the values
specified in the h.264 standard.

The lookup of the h.264 or hevc values for the respective V4L2 controls
is done by the driver that uses the sps/pps generator and not in the
generator. Therefore, it is more intuitive to define these functions
directly in the header and not in the module.
Extract the functions to the headers as static inline functions.
Also simplify the function name and add kernel-doc for the hevc
functions.

The bit rate in the SPS can be scaled by an exponent, which allows to
reduce the number of bits in the SPS in case of high bit rates.
The driver did not scale the bitrate, but used a scaling exponent of 0.

The encoder buffer serves as a cache for reference frames during the
encoding process. The encoder buffer significantly reduces the bandwidth
requirement for read accesses on the AXI ports of the VCU, but slightly
reduces the quality of the encoded video.
The encoder buffer must be configured as a whole during the firmware
initialization and later explicitly enabled for every channel that shall
use the encoder buffer.
Prior to firmware version 2019.2, it was necessary to explicitly set the
size of the encoder buffer for every channel. Since 2019.2 it is
sufficient to enable the encoder buffer and leave the rest to the
firmware. Therefore, only support the encoder buffer for firmware 2019.2
and later.

The allegro driver must ensure that the mcu and core clocks are enabled
and set to the expected clock rate before trying to load the firmware
and to reset the MCU.
Up until now, the driver assumed that the clocks are always enabled in
the PL (programming logic), because the xlnx_vcu driver did not export
the clocks to other drivers. This has changed and by explicitly enabling
the clocks in the driver, this assumption can be dropped.
It might even be possible to disable the clocks for the encoder if the
encoder is not used. However, the behavior is not documented and it
might be necessary to reinitialize the encoder after deactivating the
clocks. Play it safe by sticking to the current behavior.

The VCU provides information about its configuration in a dedicated
register space. These settings include, for example, the expected clock
rates and the configuration of the encoder buffer. In the device tree,
the settings are described by the "xlnx,vcu-settings" compatible.
The settings are needed to correctly configure the clocks and the
encoder buffer.

The mailbox is initialized after the interrupt handler is installed. As
the firmware is loaded and started even later, it should not happen that
the interrupt occurs without the mailbox being initialized.
As the Linux Driver Verification project (linuxtesting.org) keeps
reporting this as an error, add a check to ignore interrupts before the
mailbox is initialized to fix this potential null pointer dereference.

This driver is a port of the lirc_sir driver to rc-core. However, for
this driver I could not find any hardware to test, so it was done without
testing. This is a mistake.
There are clear bugs in the code. For example the two arguments
to ktime_us_delta() are reversed, which means the result is garbage.

reported an issue. So, remove this driver.

The TDA1997x (HDMI receiver) driver currently uses a specific video
format detection scheme. The frame (or field in interlaced mode), line
and HSync pulse durations are compared to those of known, standard video
modes. If a match is found, the mode is assumed to be detected,
otherwise -ERANGE is returned (then possibly ignored). This means that:
- another mode with similar timings will be detected incorrectly
(e.g. 2x faster clock and lines twice as long)
- non-standard modes will not work.
This patch replaces this scheme with a direct read of geometry
registers. This way all modes recognized by the chip are supported.
In interlaced modes, the code assumes the V sync signal has the same
duration for both fields. While this may be not necessarily true,
I can't see any way to get the "other" V sync width. This is most
probably harmless.
All tests have been performed on Gateworks' Ventana GW54xx board, with
a TDA19971 chip.

There is one build fix for Arm platforms that ended up impacting most
architectures because of the way the drivers/firmware Kconfig file is
wired up:
The CONFIG_QCOM_SCM dependency have caused a number of randconfig
regressions over time, and some still remain in v5.15-rc4. The
fix we agreed on in the end is to make this symbol selected by any
driver using it, and then building it even for non-Arm platforms with
CONFIG_COMPILE_TEST.
To make this work on all architectures, the drivers/firmware/Kconfig
file needs to be included for all architectures to make the symbol
itself visible.
In a separate discussion, we found that a sound driver patch that is
pending for v5.16 needs the same change to include this Kconfig file,
so the easiest solution seems to have my Kconfig rework included in v5.15.
There is a small merge conflict against an earlier partial fix for the
QCOM_SCM dependency problems.
Finally, the branch also includes a small unrelated build fix for NOMMU
architectures.
