linux.git/include/uapi/linux/cec.h, branch v5.18

media: include/uapi/linux/cec.h: typo: SATERDAY -> SATURDAY

2021-07-12T07:16:29+00:00

Fix typo in a define: CEC_OP_REC_SEQ_SATERDAY -> CEC_OP_REC_SEQ_SATURDAY

This isn't used yet in actual applications to the best of my knowledge,
and it certainly doesn't break the ABI since the value doesn't change.

media: cec: expose the new connector info API

2019-10-01T20:19:41+00:00

Until now the connector info API was a kernel-internal API only.
This moves it to the public API and adds the new ioctl to retrieve
this information.

CEC_OP_REC_FLAG_NOT_USED is 0 and CEC_OP_REC_FLAG_USED is 1, not the
other way around.

media: uapi/linux/cec.h: add defines for the CEC UI Command Operand

2019-10-01T20:17:51+00:00

These defines were never added to this CEC header, likely due
to laziness on the part of the original author, i.e. me.

But it is useful to have them, so add them.

Also update the cec.h.rst.exceptions file to avoid errors when
building the documentation.

media: cec: add CEC_MSG_FL_RAW flag and msg_is_raw helper function

2019-05-23T09:32:40+00:00

This adds the userspace API to send raw unchecked CEC messages.
This will require root permissions.

media: cec: add new tx/rx status bits to detect aborts/timeouts

2018-10-05T15:22:39+00:00

If the HDMI cable is disconnected or the CEC adapter is manually
unconfigured, then all pending transmits and wait-for-replies are
aborted. Signal this with new status bits (CEC_RX/TX_STATUS_ABORTED).

If due to (usually) a driver bug a transmit never ends (i.e. the
transmit_done was never called by the driver), then when this times
out the message is marked with CEC_TX_STATUS_TIMEOUT.

This should not happen and is an indication of a driver bug.

Without a separate status bit for this it was impossible to detect
this from userspace.

The 'transmit timed out' kernel message is now a warning, so this
should be more prominent in the kernel log as well.

Pull media updates from Mauro Carvalho Chehab:

 - Documentation for digital TV (both kAPI and uAPI) are now in sync
   with the implementation (except for legacy/deprecated ioctls). This
   is a major step, as there were always a gap there

 - New sensor driver: imx274

 - New cec driver: cec-gpio

 - New platform driver for rockship rga and tegra CEC

 - New RC driver: tango-ir

 - Several cleanups at atomisp driver

 - Core improvements for RC, CEC, V4L2 async probing support and DVB

 - Lots of drivers cleanup, fixes and improvements.
