    description:
      The AHB/AXI peripherals on the PolarFire SoC have reset support, so
      from CLK_ENVM to CLK_CFM. The reset consumer should specify the
      desired peripheral via the clock ID in its "resets" phandle cell.
      See include/dt-bindings/clock/microchip,mpfs-clock.h for the full list
      of PolarFire clock/reset IDs.
