Pull Documentation updates from Jonathan Corbet:
"It's been a relatively busy cycle for docs:
- A fair pile of RST conversions, many from Mauro. These create more
than the usual number of simple but annoying merge conflicts with
other trees, unfortunately. He has a lot more of these waiting on
the wings that, I think, will go to you directly later on.
- A new document on how to use merges and rebases in kernel repos,
and one on Spectre vulnerabilities.
- Various improvements to the build system, including automatic
markup of function() references because some people, for reasons I
will never understand, were of the opinion that
:c:func:``function()`` is unattractive and not fun to type.
- We now recommend using sphinx 1.7, but still support back to 1.4.

As the try_encoder_cmd is identical for many drivers, there are now
helpers for this function in the mem2mem core. Use the helper in
allegro.
This fixes the v4l2-compliance test regarding V4L2_ENC_CMD_STOP, because
the allegro-specific function rejected invalid flags.

Frequent IOMMU remappings take about 50% of CPU usage because there is
quite a lot to remap. Defer dmabuf's unmapping by 5 seconds in order to
mitigate the mapping overhead which goes away completely and driver works
as fast as in a case of a disabled IOMMU. The case of a disabled IOMMU
should also benefit a tad from the caching since CPU cache maintenance
that happens on dmabuf's attaching takes some resources.

Minor SPDX change conflict.

The __packed macro isn't available in userspace with the kernel headers.
Checkpatch asks to use the macro, which is unwanted in a case of a UAPI
header. There is no much benefit in a tight packing of the structures,
hence let's pack them manually to cleanup things a tad. Note that there
is no old-stable userspace that will suffer from this change, hence it's
fine to change the ABI. In a result also more space is reserved for a
possible future expansion of the UAPI as it was already shown that more
fields will be needed for a later SoC generations.

The kbuild documentation clearly shows that the documents
there are written at different times: some use markdown,
some use their own peculiar logic to split sections.
Convert everything to ReST without affecting too much
the author's style and avoiding adding uneeded markups.
The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- adjust title markups.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

this driver is pretty horrible from a design pov, and needs a complete
overhaul. Concrete thing that annoys me is that it looks at
registered_fb, which is an internal thing to fbmem.c and fbcon.c. And
ofc it gets the lifetime rules all wrong (it should at least use
get/put_fb_info).
Looking at the history, there's been an attempt at dropping this from
staging in 2016, but that had to be reverted. Since then not real
effort except the usual stream of trivial patches, and fbdev has been
formally closed for any new hw support. Time to try again and drop
this?

Except for driver bugs (which we'll catch with a WARN_ON) this is only

nothing the outgoing driver can do about that, and no one ever

Amlogic SoCs feature a powerful video decoder unit able to
decode many formats, with a performance of usually up to 4k60.
This is a driver for this IP that is based around the v4l2 m2m framework.
It features decoding for:
- MPEG 1
- MPEG 2
Supported SoCs are: GXBB (S905), GXL (S905X/W/D), GXM (S912)
There is also a hardware bitstream parser (ESPARSER) that is handled here.

Commit 020bc7354a6e ("media: staging/imx: Allow driver to build
if COMPILE_TEST is enabled") incorrectly assumed that the imx media
driver had no build time dependency with IMX_IPUV3_CORE.
Building on x86_64 without IMX_IPUV3_CORE causes lots of build errors
such as:
All these definitions come from the imx ipu3 core driver, so make
sure that imx media depends on IMX_IPUV3_CORE.
This reverts commit 020bc7354a6ebec980e0aedf5bedf57b42f93aca.

Mostly due to x86 and acpi conversion, several documentation
links are still pointing to the old file. Fix them.

On x86_64 when GPIOLIB is not set the following build errors
are seen:
drivers/staging/iio/addac/adt7316.c:947:3: error: implicit declaration of function 'gpiod_set_value' [-Werror=implicit-function-declaration]
drivers/staging/iio/addac/adt7316.c:1805:2: error: implicit declaration of function 'irqd_get_trigger_type' [-Werror=implicit-function-declaration]
These functions are provided by the <linux/gpio/consumer.h>
and <linux/irq.h> headers, so include them to fix these
build errors.
While at it, remove <linux/gpio.h> as this driver is a GPIO
consumer and not a GPIO driver.

In case of ioremap failure, the core code will take care of printing
the error message, so there is no need for having a local error
message in the driver.

The CSI registers are 32-bit, so using u32 type is more suitable
for storing the values from register reads.
Switch from 'unsigned long' to 'u32' type.

Currently there is a macro for reading and another macro for writing
to the CSI registers.
Functions can do parameter type checking, which leads to a safer code,
so switch from macro to function implementation.

be assigned at:
ret = mipi_csis_parse_dt(pdev, state);

Currently the return value from clk_bulk_prepare_enable() is checked,
but it is not propagate it in the case of failure.
Fix it and also move the error message to the caller of
mipi_csis_clk_enable().

Instead of filling in the struct v4l2_capability device_caps
field, fill in the struct video_device device_caps field.
That way the V4L2 core knows what the capabilities of the
video device are.
But this only really works if all drivers use this, so convert
all staging/media drivers in this patch.

Support for multiplanar and singleplanar formats is mutually exclusive,
at least in practice. In our attempt to unify support for support for
mplane and !mplane in v4l, let's get rid of the
->vidioc_enum_fmt_{vid,out}_cap_mplane() hooks and call
->vidioc_enum_fmt_{vid,out}_cap() instead.
