[PATCH 1/2] of: Add of_property_present() helper

From: Rob Herring
Date: Wed Feb 15 2023 - 16:55:54 EST


Add an of_property_present() function similar to
fwnode_property_present(). of_property_read_bool() could be used
directly, but it is cleaner to not use it on non-boolean properties.

I plan to add this for v6.3 and send most of the conversion patches in
the next cycle.
