Reid Tonking 3d6cb03905 arm: dts: k3-j7200-r5-common-proc-board: Set parent clock for clock ID 323
Previously, dynamic frequency scaling supported rates only through fixed
divison.

This virtual clock mux configuration enables more varied rates on A72
clock ID 202 by setting up the required register.
