media: cec: return -ENODEV instead of -ENXIO if unregistered

2024-04-24T11:49:55Z

If the CEC device is unregistered, then an attempt to open the device node should result in an -ENODEV error instead of -ENXIO. Document this as well in cec-func-open.rst. This is consistent with the error code returned by other file operations such as ioctl. Signed-off-by: Hans Verkuil

media: doc: properly format ToC headings

2023-11-17T20:05:26Z

"class:: toc-title" was a workaround for older Sphinx versions that are no longer supported. The canonical way to add a heading to the ToC is to use :caption:. Do that.

Document administration details about CEC devices. This was formerly documented in a cec-status.txt I kept on my website, but this really belongs here as an admin guide. Updated the original cec-status.txt, and converted it to .rst. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

2021-04-06T14:08:38Z

The rx-arb-lost error injection command only works with set to 'any'. Explicitly say so in the usage message. Also use [] to indicate that the argument is optional. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

2021-03-11T10:59:40Z

media: cec-core.rst/cec-ioc-g-mode.rst: fix typos in monitor-all description

2020-11-16T09:31:09Z

cec-core.rst was missing 'are', and cec-ioc-g-mode.rst was missing a comma. In both cases this made the description of the Monitor All functionality hard to read. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: docs: make CEC documents compatible with Sphinx 3.1+

2020-10-15T05:49:39Z

Sphinx 3.x broke support for the cdomain.py extension, as the c domain code was rewritten. Due to that, the c tags need to be re-written, in order to use the new c domain notation. Signed-off-by: Mauro Carvalho Chehab

media: docs: use the new SPDX header for GFDL-1.1 on *.rst files
