2018-10-05media: cec-gpio: select correct Signal Free TimeHans Verkuil
If a receive is in progress or starts before the transmit has a chance, then lower the Signal Free Time of the upcoming transmit to no more than CEC_SIGNAL_FREE_TIME_NEW_INITIATOR. This is per the specification requirements. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
2018-10-05media: cec: fix the Signal Free Time calculationHans Verkuil
The calculation of the Signal Free Time in the framework was not correct. If a message was received, then the next transmit should be considered a New Initiator and use a shorter SFT value. This was not done with the result that if both sides where continually sending messages, they both could use the same SFT value and one side could deny the other side access to the bus. Note that this fix does not take the corner case into account where a receive is in progress when you call adap_transmit.

2018-10-05media: cec: add new tx/rx status bits to detect aborts/timeoutsHans Verkuil
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.

2018-10-05Revert "media: dvbsky: use just one mutex for serializing device R/W ops"Mauro Carvalho Chehab
As pointed at: https://bugzilla.kernel.org/show_bug.cgi?id=199323 This patch causes a bad effect on RPi. I suspect that the root cause is at the USB out of tree RPi driver, with uses high priority interrupts instead of normal ones. Anyway, as this patch is mostly a cleanup, better to revert it.

2018-10-04media: dt-bindings: media: Specify bus type for MIPI D-PHY, others, explicitlySakari Ailus
Allow specifying the bus type explicitly for MIPI D-PHY, parallel and Bt.656 busses. This is useful for devices that can make use of different bus types. There are CSI-2 transmitters and receivers but the PHY selection needs to be made between C-PHY and D-PHY; many devices also support parallel and Bt.656 interfaces but the means to pass that information to software wasn't there. Autodetection (value 0) is removed as an option as the property could be simply omitted in that case.
