[PATCH v2 03/17] dt-bindings: soc/microchip: make systemcontroller a mfd

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Conor Dooley <conor.dooley@xxxxxxxxxxxxx>

Make the system controller on the Polarfire SoC
a "simple,mfd" so that the services can be child
nodes of the system controller node.
