2019-06-24media: coda: fix V4L2_DEC_CMD_STOP when all buffers are already consumedMarco Felsch1-0/+6
When the DEC_CMD_STOP command is issued after the context has already consumed all the queued buffers, we need to make sure to wake the destination queue with last_buffer_dequeued set, to allow userspace to make progress in its EOS handling. As there might still be picture run workers pending at that point, we need to synchronize with them, so the sequence number comparison reads stable values. reword commit message] Signed-off-by: Marco Felsch <m.felsch@pengutronix.de> Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

2019-06-24media: coda: fix last buffer handling in V4L2_ENC_CMD_STOPMarco Felsch1-0/+2
coda_encoder_cmd() is racy, as the last scheduled picture run worker can still be in-flight while the ENC_CMD_STOP command is issued. Depending on the exact timing the sequence numbers might already be changed, but the last buffer might not have been put on the destination queue yet. In this case the current implementation would prematurely wake the destination queue with last_buffer_dequeued=true, causing userspace to call streamoff before the last buffer is handled. Close this race window by synchronizing with the pic_run_worker before doing the sequence check.

2019-06-24media: marvell-ccic: provide a clock for the sensorLubomir Rintel5-181/+157
The sensor needs the MCLK clock running when it's being probed. On platforms where the sensor is instantiated from a DT (MMP2) it is going to happen asynchronously. Therefore, the current modus operandi, where the bridge driver fiddles with the sensor power and clock itself is not going to fly. As the comments wisely note, this doesn't even belong there. Luckily, the ov7670 driver is already able to control its power and reset lines, we can just drop the MMP platform glue altogether. It also requests the clock via the standard clock subsystem. Good -- let's set up a clock instance so that the sensor can ask us to enable the clock. Note that this is pretty dumb at the moment: the clock is hardwired to a particular frequency and parent. It was always the case. Signed-off-by: Lubomir Rintel <lkundrak@v3.sk> Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

The __packed macro isn't available in userspace with the kernel headers. Checkpatch asks to use the macro, which is unwanted in a case of a UAPI header. There is no much benefit in a tight packing of the structures, hence let's pack them manually to cleanup things a tad. Note that there is no old-stable userspace that will suffer from this change, hence it's fine to change the ABI. In a result also more space is reserved for a possible future expansion of the UAPI as it was already shown that more fields will be needed for a later SoC generations.

To fix the bug, this commit adjusts the capturing window register setting to 1728 if detected width is 1680. The compression window register setting will be kept as the original width so output result will be the same.
