15 * Let each exported clock get a unique index, which is used on DT-enabled
16 * platforms to lookup the clock from a clock specifier. These indices are
17 * therefore considered an ABI and so must not be changed. This implies
18 * that new clocks should be added either in free spaces between clock groups
19 * or at the end.
