[PATCH 0/2] driver core: provide and use device_match_fwnode_ext()

Posted by Bartosz Golaszewski 1 month, 1 week ago

In GPIOLIB, during fwnode lookup, after having resolved the consumer's
reference to a specific fwnode, we only match it against the primary
node of the controllers. Let's extend that to also the secondary node by
providing a new variant of device_match_fwnode() and using it in GPIO
core.
