media: bcm2835-unicam: Add support for CCP2/CSI2 camera interface 



Add a driver for the Unicam camera receiver block on BCM283x processors.
It is represented as two video device nodes: unicam-image and
unicam-embedded which are connected to an internal subdev (named
unicam-subdev) in order to manage streams routing.

	  Say Y here to enable support for the BCM283x/BCM271x CSI-2 receiver.









	  This is a V4L2 driver that controls the CSI-2 receiver directly,









	  independently from the VC4 firmware.



















	  This driver is mutually exclusive with the use of bcm2835-camera. The









	  firmware will disable all access to the peripheral from within the









	  firmware if it finds a DT node using it, and bcm2835-camera will









	  therefore fail to probe.



















	  To compile this driver as a module, choose M here. The module will be









	  called bcm2835-unicam.
