[PATCH 1/1] of/documentation: Update s5m8767-regulator bindings document

[Sachin Kamat]

s5m8767 regulator is used on Exynos platforms which use pin controller
to configure GPIOs. Update the example accordingly.

This smells bad, why does a driver using GPIOs through the GPIO API see
a change in the binding?

There is no change in the bindings, but just a correction in the
documentation to reflect the
implementation. Earlier when Samsung platforms did not have pinctrl
driver, legacy GPIO driver
was used which took those 5 parameters. Now since we are using
pinctrl, we need only 3 parameters.
The document was somehow not updated to reflect this change.

So there was a previous change to the code that mistakenly didn't update
the binding document?

Yes, that is correct. In fact the changes happened during the review
process itself. Hence there is no commit history of this change.
However the binding document was not updated during the review phase
and the first version itself got committed as it is.

Applied, thanks.  Please use subject lines that match the subsystem and
try to make your changelogs clearer.
