What is the purpose of having num-drc-cfgs? We can tell how large drc-cfg-regs is so it just seems redundant.
Can you please point me to any reference implementation doing this ?
of_property_read_variable_uX_array() should do what you want, you can also use of_property_count_elems_of_size(). The main DT API header is linux/of.h.
