676d2d4f08 [media] sh_mobile_ceu_camera: add asynchronous subdevice probing support 
Use the v4l2-async API to support asynchronous subdevice probing,
including the CSI2 subdevice. Synchronous probing is still supported too.

6b526fed0e [media] V4L: sh_mobile_csi2: switch away from using the soc-camera bus notifier 
This moves us one more step closer to eliminating the soc-camera bus
and devices on it. Besides, as a side effect, CSI-2 runtime PM on
sh-mobile secomes finer grained now: we only have to power on the
interface, when the device nodes are open.

077e2c10c9 V4L/DVB: V4L2: soc-camera: add a MIPI CSI-2 driver for SH-Mobile platforms 
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.
