I boot tested this on am335x-bone and am335x-boneblack boards and could
successfully boot and i even checked the regulators registered am335x-bone:
cat /sys/class/regulator/regulator.*/name
regulator-dummy
vmmcsd_fixed
DCDC1
DCDC2
DCDC3
LDO1
LDO2
LDO3
LDO4
Looks good to me. For am335x-bone and am335x-boneblack you can add
