The bindings like s2mps11,buck6-ramp-enable or s2mps11,buck2-ramp-delay
where ignored. They were never parse by s2mps11 regulator driver. Also
the values used in these bindings were equal to default reset values of
S2MPS11 device. It is safe to remove them.

The patch looks good to me.
Reviewed-by: Javier Martinez Canillas <javier@osg.samsung.com>
On a related note, the s5m8767 regulator driver parses similar DT properties
("s5m8767,pmic-buck-ramp-delay", "s5m8767,pmic-buck2-ramp-enable", etc) that
are not in Documentation/devicetree/bindings/regulator/samsung,s5m8767.txt.
So those should either be added to the binding doc or removed from the driver
if are not correct (I don't have documentation for the s5m8767 PMIC but the
DT properties are not use by any DTS in mainline using the s5m8767 PMIC).

That's the grey area. :) I mean that instead of making these implemented
bindings an interface, they should rather be converted to standard
regulator bindings. However the device is quite old, not used on newer
boards, so there is no interest in improving this. In the same time
removal of this code is not strictly necessary. Its existence does not hurt.
Best regards,
Krzysztof
