+
+description:
+  The ES9039Q2M is a 32-bit two-channel audio DAC supporting PCM to 768 kHz,
+  DSD64 to DSD1024, DoP and S/PDIF. It is controlled over I2C or SPI when the
+  MODE pin selects software mode; this binding covers the I2C interface. The
+  part contains an asynchronous sample rate converter, so the system clock need
+  not be synchronous with the audio bit or frame clocks.
