As explained in my previous mail, MIPI DSI panels should be supported in a 
similar way as MIPI DPI panels. The DSI API is missing, but only because 
nobody has implemented it yet.

That's the display controller driver. A sample implementation is available at 
http://git.linuxtv.org/pinchartl/fbdev.git/shortlog/refs/heads/lcdc-panel, see 
the "fbdev: sh_mobile_lcdc: Add generic panel support" and "fbdev: 
sh_mobile_lcdc: MIPI DBI bus support" patches.
