As per Sony IMX274 Y_OUT_SIZE should be the height of effective image output from the sensor which are the actual total lines sent over MIPI CSI to receiver. So, Y_OUT_SIZE should be same as crop height and this patch fixes it. Signed-off-by:

Add support for suspend and resume by stopping and starting the video pipeline while still retaining all buffers given to the driver by user-space and internally allocated ones, this gives the application a seamless experience. Buffers are never returned to user-space unprocessed so user-space don't notice when suspending. When resuming the driver restarts the capture session using the internal scratch buffer, this happens before user-space is unfrozen, this leads to speedy response times once the application resumes its execution. As the entire pipeline is stopped on suspend all subdevices in use are also stopped, and if they enter a shutdown state when not streaming (such as the R-Car CSI-2 driver) they too will be suspended and resumed in sync with the VIN driver. To be able to do keep track of which VINs should be resumed a new internal state SUSPENDED is added to recode this. Signed-off-by:

To support suspend and resume the ability to start and stop the hardware needs to be available internally in the driver. Currently this code is in the start and stop callbacks of the vb2_ops struct. In these callbacks the code is intertwined with buffer allocation and freeing. Prepare for suspend and resume support by breaking out the hardware start/stop code into new methods. Signed-off-by:

When returning buffers to user-space it's no longer needed to examine the buffers given to hardware as recent changes guarantees the only buffer present in the hardware registers when the driver is not in the running state is the scratch buffer. Remove the special case and rename the function to better describe it now only deals with buffers queued to the driver but not yet recorded in the hardware registers. Signed-off-by:

In its early stages the VIN driver did not use an internal scratch buffer. This leads to a unnecessary complex start and stop behavior, specially for TB/BT. The driver now always allocates a scratch buffer to deal with buffer under-runs, use the scratch buffer to also simplify starting and stopping. When capture is starting use the scratch buffer instead of a user-space buffers while syncing the driver with the hardware state. This allows the driver to know that no user-space buffer is given to the hardware before the running state is reached. When capture is stopping use the scratch buffer instead of leaving the user-space buffers in place and add a check that all user-space buffers are processed by the hardware before transitioning from the stopping to stopped state. This allows the driver to know all user-space buffers given to the hardware are fully processed. This change in itself does not improve the driver much but it paves the way for future simplifications and enhancements. One direct improvement of this change is that TB/BT buffers returned to user-space while stopping will always contain both fields, that was not guaranteed before. Signed-off-by:
