| Subject | [PATCH 2/15] clk: sunxi-ng: Pass the parent and a pointer to the clocks round rate |

The clocks might need to modify their parent clocks. In order to make that
possible, give them access to the parent clock being evaluated, and to a
pointer to the parent rate so that they can modify it if needed.
