Also here a couple of things are missing (presumably, for other SoCs you
need the same):
Thank you for testing the patch set. I'll integrate the modification in the 
next version for r8a7778, r8a7779 and r8a7790.

As the gpio-ranges property specifies the number of GPIOs handled by the 
controller, what's your opinion on dropping the #gpio-lines property from the 
bindings ?
