Yes, please refer to Documentation/gpio/board.txt.

Ah, dd34c37aa3 ("gpio: of: Allow -gpio suffix for property names")
changed that, so both variants are now supported.

OK good catch.  I will look into it.

Does the gpiod interface handle both pdata as well as dt?

I am looking for that restriction in the code.  But don't see it.

New code for GPIO handling should use the new gpiod interface.
See include/linux/gpio/consumer.h, or the sta350 codec driver.

For that to work, you also need to rename the property to
'enable-gpios', even though there's only one.

 See include/linux/gpio/consumer.h, or the sta350 codec driver.

OK good catch.  I will look into it.

Does the gpiod interface handle both pdata as well as dt?

 For that to work, you also need to rename the property to
 'enable-gpios', even though there's only one.

I am looking for that restriction in the code.  But don't see it.
Will dig some more here.
