So no, don't *add* any more of these functions. Only add the generic
version. And if your driver isn't using the generic property
functions... fix it.

As far as I can see, all the device_property_* functions are grounded on their
of_property_*, acpi_property_* etc counterparts and functions reading specific
elements (the _index variants) are currently not available at all.

drivers/base/property.c:
#define OF_DEV_PROP_READ_ARRAY(node, propname, type, val, nval)                         \
        (val) ? of_property_read_##type##_array((node), (propname), (val), (nval))      \
              : of_property_count_elems_of_size((node), (propname), sizeof(type))

So even if you're using the device_property_* functions you'd still need
a match in the underlying functions or am I missing something?

Yes, but the underlying function should never be used directly by
drivers. And should probably be prefixed with __ or marked deprecated
(with an override in its one genuine call site).
