12description:
13  Clock related registers are spread among the chip control registers. Berlin
14  clock node should be a sub-node of the chip controller node. Marvell Berlin2
15  (BG2, BG2CD, BG2Q) SoCs share the same IP for PLLs and clocks, with some minor
16  differences in features and register layout.
