2018-05-17media: v4l: vsp1: Reset the crop and compose rectangles in the set_fmt helperLaurent Pinchart1-55/+4
To make vsp1_subdev_set_pad_format() usable by entities that support selection rectangles, we need to reset the crop and compose rectangles when setting the format on the sink pad. Do so and replace the custom set_fmt implementation of the histogram code by a call to vsp1_subdev_set_pad_format(). Resetting the crop and compose rectangles for entities that don't support crop and compose has no adverse effect as the rectangles are ignored anyway.

Adopt the SPDX license identifier headers to ease license compliance management. All files in the driver are licensed under the GPLv2+ except for the vsp1_regs.h file which is licensed under the GPLv2. This is likely an oversight, but fixing this requires contacting the copyright owners and is out of scope for this patch. While at it fix the file descriptions to match file names where copy and paste error occurred.

2018-05-04media: v4l: vsp1: Store pipeline pointer in vsp1_entityLaurent Pinchart1-1/+1
Various types of objects subclassing vsp1_entity currently store a pointer to the pipeline. Move the pointer to vsp1_entity to simplify the code and avoid storing the pipeline in more entity subclasses later.
