17 * struct clk_ops - standard clock operations
18 * @set_rate: set the clock rate, see clk_set_rate().
19 * @get_rate: get the clock rate, see clk_get_rate().
20 * @round_rate: round a given clock rate, see clk_round_rate().
21 * @set_parent: set the clock's parent, see clk_set_parent().
22 *
23 * Group the common clock implementations together so that we
24 * don't have to keep setting the same fiels again. We leave
25 * enable in struct clk.
26 *
27 * Adding an extra layer of indirection into the process should
28 * not be a problem as it is unlikely these operations are going
29 * to need to be called quickly.
