This is ugly. Looking at simplefb_clocks_get(), of_clk_get_parent_count() seems useful for clock consumers as well as for clock providers. Unfortunately, we do not have a good home for declarations shared between consumers and providers. Create a new header , and move it over to it. This header must be included via or (this is why it is prefixed with double-underscore). Add #error so the build terminates if it is included directly.
