Subject[PATCH v6 41/41] ARM: dts: da850: Add clocks
Date
This adds clock provider nodes for da850 and wires them up to all of the
devices.

Signed-off-by: David Lechner <david@lechnology.com>
---

v6 changes:
- updated for device tree bindings changes earlier in this series
- use single async2 clock instead of duplicate fixed factor clocks
- add clock-names property to mdio node
