media: cec: core: add new CEC_MSG_FL_REPLY_VENDOR_ID flag

2024-08-05T07:38:46Z

If this flag is set, then the reply is expected to consist of the CEC_MSG_VENDOR_COMMAND_WITH_ID opcode followed by the Vendor ID (as used in bytes 1-4 of the message), followed by the struct cec_msg reply field. Note that this assumes that the byte after the Vendor ID is a vendor-specific opcode. This flag makes it easier to wait for replies to vendor commands, using the same CEC framework support for waiting for regular replies. Support for this flag is indicated by setting the new CEC_CAP_REPLY_VENDOR_ID capability. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

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.

media: admin-guide: cec.rst

2022-11-25T07:39:21Z

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

media: cec-ioc-receive.rst: clarify sequence and status fields

2021-11-15T08:12:03Z

Improve the documentation for CEC_RECEIVE/TRANSMIT w.r.t. the sequence and tx/rx_status fields. Also remove a duplicate tx_status description. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: cec/core: clarify rx-arb-lost usage message

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

media: docs: uAPI: fix table output in LaTeX/PDF format

2021-03-11T10:59:40Z

There are lots of tables that are not properly displayed in LaTeX/PDF. Fix the tablecolumns, add longtable where needed and LaTeX formatting macros, in order to address such issues. Signed-off-by: Mauro Carvalho Chehab

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

2020-09-01T12:13:30Z

SPDX v3.10 gained support for GFDL-1.1 with no invariant sections: https://spdx.org/licenses/GFDL-1.1-no-invariants-or-later.html So, remove the license text, replacing them by this new SPDX license. Signed-off-by: Mauro Carvalho Chehab
