+ * Name: esp32s3_es8311_initialize

+ * Description:
+ *   This function is called by platform-specific, setup logic to configure

+ *   as /dev/audio/pcm[x] where x is determined by the I2S port number.
+ *
+ * Input Parameters:
+ *   i2c_port  - The I2C port used for the device
+ *   i2c_addr  - The I2C address used by the device
+ *   i2c_freq  - The I2C frequency used for the device
+ *   i2s_port  - The I2S port used for the device
+ *
+ * Returned Value:
+ *   Zero is returned on success.  Otherwise, a negated errno value is
+ *   returned to indicate the nature of the failure.
