media: add SPDX header to media uAPI files

All those files are under GFDL 1.1 or later, with no invariant sections. Tag them as such. Signed-off-by: Mauro Carvalho Chehab

media: remove text encoding from rst files

2018-12-05T15:37:18Z

This is not needed there. Also, the same UTF-8 encoding should be used on all documents. Signed-off-by: Mauro Carvalho Chehab

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

2018-10-05T15:22:39Z

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.

media: cec-core.rst/cec-ioc-receive.rst: clarify CEC_TX_STATUS_ERROR

2017-09-23T11:41:38Z

CEC_TX_STATUS_ERROR can be used if the HW cannot tell LOST_ARB and LOW_DRIVE apart, or when some other error occurs. It is not a replacement for NACK. So the hardware must be able to tell the difference between OK, NACK and 'something else'. Clarify the documentation (both public and kernel API) on this point. Also fix two small typos (this messages -> this message). Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
