[libcamera-devel] [PATCH v4 3/6] libcamera: CameraSensorProperties: Adds table of v4l2 index and test pattern

[Hirokazu Honda]

In V4L2 API, a driver returns an index (also with a name) to
represent a test pattern, but it is a driver specific what test
pattern is represented by the index. Therefore, this adds a
mapping table from the index and a test pattern into a static
configuration of a sensor.
