The patch looks good to me.

Reviewed-by: Javier Martinez Canillas <javier@....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).

Best regards,
