media: v4l: fwnode: Rename v4l2_async_register_subdev_sensor_common

2021-04-06T12:36:54+00:00

Rename v4l2_async_register_subdev_sensor_common as
v4l2_async_register_subdev_sensor. This is a part of the effort to make
the long names present in V4L2 fwnode and async frameworks shorter.

The :c:function: tag evaluation depends on Sphinx version 2 or 3.
Use a syntax that should work with both versions.

media: Remove the legacy v4l2-clk API

2021-02-06T08:39:44+00:00

The V4L2 temporary clock helper API, was introduced
in late 2012 and, as mentioned in the documentation,
meant to be replaced by the generic clock API,
once the generic clock framework became available
on all relevant architectures.

The generic clock API is a well-established API (since a few
years now). The last few media capture drivers and sensors
using v4l2-clk have been converted to the generic clock framework.

We can now remove the v4l2-clk API.

media: Clarify v4l2-async subdevice addition API

2021-02-06T08:30:10+00:00

Now that most users of v4l2_async_notifier_add_subdev have been converted,
let's fix the documentation so it's more clear how the v4l2-async API
should be used.

Document functions that drivers should use, and their purpose.

media: hdmi: cec: replace broken link to HDMI specs

2021-01-27T13:42:43+00:00

Current link died, according to Wayback Machine, back in 2017. And the
website is completely down since 2019. Moreover, there was a custom
cover on that PDF, i.e. it was modified.

According to HDMI licence agreement (LA), HDMI specification and technical
information are supposed to be hosted on www.hdmi.org exclusively, and not
redistributed by third-parties.

Sure, there are still many more or less reliable "mirrors" out there with
a direct download straight from a search engine's page. However, for
example, from FPGA4fun[1] website it was removed "per HDMI LA request".

Unfortunately, the official download page is protected by email CAPTCHA,
but that seems to be the only legit way to obtain a copy.
