GPIO library does copy the of_node from the parent device of
the GPIO chip, there is no need to repeat this in the individual
drivers. Remove these assignment all at once.

For the details one may look into the of_gpio_dev_init() implementation.

GPIO library does copy the of_node from the parent device of
the GPIO chip, there is no need to repeat this in the individual
drivers. Remove these assignment all at once.

For the details one may look into the of_gpio_dev_init() implementation.

When creating MFD platform devices the firmware node is left unset.
This, in particular, prevents GPIO library to use it for different
purposes. Propagate firmware node from the parent device and let
GPIO library do the right thing.

While at it, slightly modify the headers to reflect the usage of APIs.

He-h, updated code, updated bugs...

Linus, can you, please, apply the first patch if you have no objections, so I
won't spam a lot of people again with no changes beneath?

I came across the same thing this week. By populating the of_compatible
field of the mfd_cell, the child device will have the appropriate
firmware node populated. Unfortunately that currently means that I'll
have to put every device type in the MFD instead of in an of_match_table
in the child driver itself. Figuring that out is one of the next things
on my list.
