SPI slave nodes must be children of the SPI master node and can contain

properties described in Documentation/devicetree/bindings/spi/spi-bus.txt

the following properties.



Required properties:

- compatible:     Should contain:

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

                  inverse clock polarity (CPOL) mode.

- spi-cpha:       Empty property indicating device requires

                  shifted clock phase (CPHA) mode.
