[PATCH v6 2/8] dt-bindings: clock: r9a06g032-sysctrl: Reference the DMAMUX subnode

[Miquel Raynal <miquel.raynal@xxxxxxxxxxx>]

This system controller contains several registers that have nothing to
do with the clock handling, like the DMA mux register. Describe this
part of the system controller as a subnode.
