[PATCH v8 42/42] ARM: dts: da850: Add clocks

David Lechner
2018-03-16T03:43:25Z

This adds clock provider nodes for da850 and wires them up to all of the
devices.

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

v8 changes:
- fix typo in clock-names property of psc0
- added power-domains properties to nodes that define that property in their
device tree bindings

v7 changes:
- move ref_clk frequency to board-specific DT files
- enable sata_refclk in da850-lcdk.dts
- drop async2 fixed factor clock
- add power-domains for devices that use them
- fix USB PHY clock-names property
- move assigned-clocks to PSC device node
- drop clocks property from devices that don't use it (e.g. EDMA)
- add clock to RTC node
- add clock-ranges to usb0 and aemif nodes
- add clock-names property to aemif node
- fix typo in psc1 clock-names

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
