Changes in v3:
   - Use a separate yaml file to describe the common properties
     for all the dsi phy versions (Stephen Boyd)
   - Remove soc from examples (Stephen Boyd)
   - Add description for register property

Changes in v4:

"Reference to the 0.9V supply for the PLL." would have been sufficient.

But overall I think the patch looks good.

Please add Acked-by/Reviewed-by tags when posting new versions. However,
there's no need to repost patches *only* to add the tags. The upstream
maintainer will do that for acks received on the version they apply.

If a tag was not added on purpose, please state why and what changed.
