[PATCH 0/2] device property: Warn on (of|fwnode|device)_property_read_bool() for non-boolean properties

[Rob Herring (Arm)]

This series makes using (of|fwnode|device)_property_read_bool() on 
non-boolean properties give a warning when used with DT. This has been 
deprecated behavior for a while now. Soon we will add yet another 
variant of this function with a Rust binding[1].

Why not put the warning in the fwnode code? The fwnode code doesn't know 
the property's type as that depends on the firmware. For DT, a boolean 
is a property with no value.

Perhaps the ACPI backend should have a warning too? I looked briefly at 
it, but I don't have a clue how or if that can be detected. Doesn't look 
like there's a specific type for booleans. In any case, that would be an 
additional change on top of this series.
