Subject: [PATCH] dt-bindings: hwmon: pmbus: Add bindings for MPS MP297x
Remove mps297x from trivial-devices as it requires
additional properties and does not fit into the trivial
devices category.
Add new bindings for MPS mp2971, mp2973 & mp2975.
It is Dual-Loop, Digital Multi-Phase Controller with PMBUS
interface
