The driver is used only on Exynos based boards with DTS support.
Convert the driver to DTS-only version. This simplifies a little the
code:
1. No dead (unused) entries in platform_data structure.
2. More code removed.
3. Regulator driver does not depend on allocated memory
   from MFD driver.
4. It makes also easier extending the regulator driver.

Add to the max77686 MFD driver dependency on CONFIG_OF because without
DTS the regulator drivers won't bind.

Noooo, don't apply it. It depends on previous patches removing the board
file support from regulators.

If the patch looks OK, please only ack it. I would like to push
everything through regulator tree.

Best regards,

Very well, patch dropped.

As long as Mark puts it on a succinct tagged branch it can go in
through his tree:

Acked-by: Lee Jones <lee.jones@linaro.org>

Mark,
  Please send me the tag to pull from once applied, thanks.
