Check return value from call to devm_kzalloc() in order to prevent a NULL pointer dereference. This issue was detected with the help of Coccinelle. Fixes: 4a5f8ae5 ("[media] davinci: vpif_capture: get subdevs from DT when available") Signed-off-by:

There is no need to #define the license of the driver, just put it in the MODULE_LICENSE() line directly as a text string. This allows tools that check that the module license matches the source code license to work properly, as there is no need to unwind the unneeded dereference.

time_to_tm() takes a time_t value that overflows in 2038 on 32-bit systems. time64_to_tm() doesn't have this problem, so let's use that in combination with ktime_get_real_seconds() to read a 64-bit time value. Signed-off-by:

According to i.MX VPU API Reference Manuals the MJPG video codec is referenced to by number 7, not 3. Also Philipp pointed out that this value is only meant to fill in CMD_ENC_SEQ_COD_STD for encoding, only on i.MX53. It was never written to any register, and even if defined correctly, wouldn't be needed for i.MX6. So avoid confusion and remove this definition. Signed-off-by:

When the device is being unregistered disable the hardware, don't wait until cec_delete_adapter is called as the hardware may have disappeared by then. This would be the case for hotplugable devices. Signed-off-by:

Hans Verkuil authored
Some devices can monitor the CEC pin using an interrupt, but you only want to enable the interrupt if you actually switch to pin monitoring mode. So add a new op that is called when pin monitoring needs to be switched on or off. Also fix a small bug where the initial CEC pin event was sent again when calling S_MODE twice with the same CEC_MODE_MONITOR_PIN mode. Signed-off-by:

The firmware timestamp is an unsigned 32-bit value, but we copy it into a signed 32-bit variable, so we can theoretically get an overflow in the calculation when the timestamp is between 2038 and 2106. This changes the temporary variable to time64_t and changes the deprecated time_to_tm() over to time64_to_tm() accordingly. There is still an overflow in y2106, but that is a limitation of the firmware interface, not a kernel problem. Signed-off-by:

Add support for the test_pattern control and the h/vflip controls. This makes it possible to switch to more interesting test patterns and to test control handling in v4l-subdevs. There are more tpg-related controls that can be added, but this is a good start. Signed-off-by:

When used as part of a display pipeline, the VSP is stopped and restarted explicitly by the DU from its suspend and resume handlers. There is thus no need to stop or restart pipelines in the VSP suspend and resume handlers, and doing so would cause the hardware to be left in a misconfigured state. Ensure that the VSP suspend and resume handlers do not affect DRM-based pipelines. Signed-off-by:

It is possible to call STREAMON without the minimum number of buffers queued. In this case the vb2_queue state will be set to streaming but the start_streaming vb2_op will not be called. Later when enough buffers are queued, start_streaming will be called but vb2_is_streaming will already return true. Also removed the queue state check in stop_streaming since it's not valid there either. Signed-off-by:

Using the ARRAY_SIZE macro improves the readability of the code. Also, it is not always useful to use a variable to store this constant calculated at compile time.

The current implementation has to search the list of controls for the pixel rate control, each time it is set. This can be optimised easily by storing the ctrl pointer in the CSI/TX object, and referencing that directly. While at it, fix up a missing blank line also highlighted in review comments.
