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@bootlin.com> --- Changes in v3: - Move the omap.yaml binding change in another patch. Changes in v2: - Used generic pmic node name. - Add regulator prefix to fixed regulator node name. - Add the compatible to omap.yaml binding --- arch/arm/boot/dts/ti/omap/Makefile | 1 + arch/arm/boot/dts/ti/omap/am335x-bonegreen-eco.dts | 169 +++++++++++++++++++++ 2 files changed, 170 insertions(+)
