Got it.

This driver is DT only, would it make more sense to just add a dependency on CONFIG_OF in the Kconfig? I don't see many other drivers that are DT only doing this, the driver should compile just fine without OF enabled, it just wont have DT functionality, so is it really dependent on OF? The of_match_ptr(x) macro looks to be useful when the x is conditionally compiled in, but in my case the x (my of_device_id table) is always compiled.
