These formats store the color information of the image in a geometrical representation. The colors are mapped into a cylinder, where the angle is the HUE, the height is the VALUE and the distance to the center is the SATURATION. This is a very useful format for image segmentation algorithms. Signed-off-by:

Delay suspending the device by 1000 ms by default. This is done on explicit power off through s_power() callback, through releasing the file descriptor, NVM read or when the probe finishes. Signed-off-by:

The dev field of the v4l2_subdev was left NULL for the pixel array and binner sub-devices. Fix this. Signed-off-by:

Checking that the mutex is not acquired is unnecessary for user processes are stopped by this point. Drop the check. Signed-off-by:

Don't complain about a failure to compute the pre_pll divisor. The function is used to determine whether a particular combination of bits per sample value and a link frequency can be used, in which case there are lots of unnecessary driver messages. During normal operation the failure generally does not happen. Use dev_dbg() instead. Signed-off-by:

The first time the sensor is powered on, the information is not yet available. Signed-off-by:

The media bus code obtained for try format may have been a code that the sensor did not even support. Use a supported code with the current pixel order. Signed-off-by:

The code probably has been unindented at some point but rewrapping has not been done. Do it now. Also remove a useless memory allocation failure message. Signed-off-by:

Besides the image data, SMIA++ compliant sensors also provide embedded data in form of registers used to capture the image. Store this information for later use in frame descriptor and routing. Signed-off-by:

Replace plain value 2 with SMIAPP_PADS when referring to the number of pads. Signed-off-by:

The initialisation of the source sub-device is somewhat different as it's not created by the smiapp driver itself. Remove redundancy in initialising the two kind of sub-devices. Signed-off-by:

The information gathered during frame format reading will be required earlier in the initialisation when it was available. Also return an error if frame format cannot be obtained. Signed-off-by:

The smiapp_probe() is the sole caller of smiapp_init(). Unify the two. Signed-off-by:

If the registered() callback failed, resources were left unaccounted for. Fix this, as well as add unregistering the sub-devices in driver unregistered() callback. Signed-off-by:

Sakari Ailus authored
Initialise the sensor in probe. The reason why it wasn't previously done in case of platform data was that the probe() of the driver that provided the clock through the set_xclk() callback would need to finish before the probe() function of the smiapp driver. The set_xclk() callback no longer exists. Signed-off-by:

The same pixel array size is required for the active format of each sub-device sink pad and try format of each sink pad of each opened file handle as well as for the native size rectangle. Signed-off-by:

pdev is being null checked, however, prior to that it is being dereferenced by platform_get_drvdata. Move the assignments of vpu and run to after the pdev null check to avoid a potential null pointer dereference. Signed-off-by:
