Some SH-Mobile SoCs implement a MIPI CSI-2 controller, that can interface to several video clients and send data to the CEU or to the Image Signal Processor. This patch implements a v4l2-subdevice driver for CSI-2 to be used within the soc-camera framework, implementing the second subdevice in addition to the actual video clients.
