Required properties:

- compatible:     Should contain:

                  "qcom,spi-msm-codec-slave" for external codec control



- reg:            Chip select address of device.



- spi-max-frequency: Maximum SPI clocking speed of device in Hz.



Optional properties:

- spi-cpol:       Empty property indicating device requires
