I initially sent this as part of the gpio-mockup overhaul but since these patches are indepentent and the work on gpio-mockup may become more complicated - I'm sending these separately.
The only change is adding additional property helpers to count strings in array.
Bartosz Golaszewski (3): device: property: add helpers to count items in string arrays gpiolib: generalize devprop_gpiochip_set_names() for device properties gpiolib: unexport devprop_gpiochip_set_names()
Ha-ha, OF unittest is of_node centric. definitely there is no backed device.
Bart, it seems we are stuck with fwnode interface.
