[v2] ARM: dts: microchip: sama7d65: Add GPIO buttons and LEDs

[PATCH v2] ARM: dts: microchip: sama7d65: Add GPIO buttons and LEDs

Posted by Ryan.Wanner@microchip.com 2 weeks ago

From: Ryan Wanner <Ryan.Wanner@microchip.com>

Add the USER button as a GPIO input as well as add the LEDs and enable
the blue LED as a heartbeat.

Signed-off-by: Ryan Wanner <Ryan.Wanner@microchip.com>

Changes v1 -> v2:
- Remove the label node in the LEDs.
- Use properties color and function to describe the LEDs.
- Add phandles for the LEDs.
