      7title: Rockchip PDM controller
      8
      9description:
     10  The Pulse Density Modulation Interface Controller (PDMC) is
     11  a PDM interface controller and decoder that support PDM format.
     12  It integrates a clock generator driving the PDM microphone
     13  and embeds filters which decimate the incoming bit stream to
     14  obtain most common audio rates.
