I don't have any concern with the use of a proper gpio driver to model
the implementation, but if I understand correctly this relationship
between gpio controller and gpio consumer is strictly internal to "the
PCI device".
Is this connection variable or is the link merely expressed in
DeviceTree to mitigate the fact that you choose to implement the
responsibilities of the two parts split into two device drivers?
Are there other consumers of these TC956x gpios which would result in a
board designer (and hence dts author) to ever reference this
gpio-controller in a different way?
Regards,
Bjorn
