PATCH 2/2 ARM64: dts: marvell: enable USB host on Armada-8040-DB
In reply to Thomas PetazzoniFrom: Grzegorz Jaszczyk <[email protected]>
Enable USB host on Armada-8040-DB by adding USB PHY nodes for the following ports:
- host 0 and 1 of CPM
- host 0 of CPS
These PHY are enabled by lanes coming from regulators based on two I2C expanders.
