Subject: [PATCH v2 4/5] arm: dts: omap: Add support for BeagleBone Green
Eco board
SeeedStudio BeagleBone Green Eco (BBGE) is a clone of the BeagleBone Green
(BBG). It has minor differences from the BBG, such as a different PMIC,
a different Ethernet PHY, and a larger eMMC.
Signed-off-by: Kory Maincent <kory.maincent@...tlin.com>
---
Changes in v2:
- Used generic pmic node name.
- Add regulator prefix to fixed regulator node name.
- Add the compatible to omap.yaml binding
