There are two big tables here that are very hard to adjust its

The first one would fit into one page, but the latex.py logic

It is painful to put code/verbatim code in bold. It seems that
the only way is to arrange it like:
``foo``

At least on LaTeX output, when this happens, the "foo" string
is not hidentable/breakable. The entire string should fit into
a single line.

Newer Amlogic platforms (Meson 8b and GXBB) use a slightly different

Historically, mdev argument name was being used on both struct
media_device and struct media_devnode. Recently most occurrences of mdev
referring to struct media_devnode were replaced by devnode, which makes
more sense. Fix the last remaining occurrence.

Hi folks,
Here's the second version of the media reference patchset I've been
working on for some time.
The lifetime of the media device (and media devnode) is now bound to that
of struct device embedded in it and its memory is only released once the
last reference is gone: unregistering is simpl

Reuse existing functionality from memdup_user() instead of keeping
duplicate source code.
This issue was detected by using the Coccinelle software.

A few update suggestions were taken into account
from static source code analysis.

Use memdup_user() rather than duplicating its implementation

In all_dev_types2s: don't try to erase the last two characters in the
string if it is empty.
This was fixed in cec-ctl, so the same fix is applied to cec-compliance
and cec-follower.

The functions might need to modify the state to store memory-related
data.

The new rcar_fcp_get_device() function retrieves the struct device
related to the FCP device. This is useful to handle DMA mapping through
the right device.

The display buffers must be mapped for DMA through the device that
performs memory access. Expose an API to map and unmap memory through
the VSP device to be used by the DU.

This patch series fixes the rcar-du-drm driver to support VSP plane sources
with an IOMMU. It is available for convenience at
