[PATCH v6 41/41] ARM: dts: da850: Add clocks
David Lechner
david at lechnology.com
Sat Jan 20 09:14:20 PST 2018
This adds clock provider nodes for da850 and wires them up to all of the
devices.
Signed-off-by: David Lechner <david at 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
