Looking to this code I just realized it would be nice to have

{of,device}_property_read_bitmask() where bitmask_parse() is called.

Since it related to change a binding, I would really take couple of
days to hear other opinions.

In the above case, you need to supply a string, like

"1-5,16,18,25"
