Hi Jai,                                                                      
                                                                             

Add a V4L2 subdev driver for the Sony IMX678 image sensor.                 
                                                                           
IMX678 is a diagonal 8.86 mm (Type 1/1.8) CMOS active pixel type           
solid-state image sensor with a square pixel array and 8.40 M effective    
pixels.                                                                    
                                                                           
The following features are supported by this driver:                       
- MIPI RAW12 output                                                        
- Monochrome and Color (Bayer filter) variants                             
- Multiple input clock frequencies                                         
- Multiple link frequencies                                                
- VBLANK and HBLANK control for variable framerate                         
- VFLIP and HFLIP control for flipping readout                             
- Exposure and analogue gain control                                       
- Test pattern control                                                     
                                                                           
Following features are not currently supported:                            
- MIPI RAW10 output                                                        
- Pixel-perfect crop reporting, accounting for the shift-by-1 when         
  doing HFLIP/VFLIP where the sensor maintains RGGB bayer ordering         
                                                                           
Along with the ones below which depend on the new raw sensor model:        
- Embedded data stream                                                     
- Freely configurable cropping                                             
- Increased framerate when cropping                                        
- 2x2 binning support

I think there is no need for a new revision for this minor style fix. 
It can be addressed during the merge.
