+Required properties:
+ - compatible: should be "adi,ad2s90"
+ - reg: SPI chip select number for the device
+ - spi-max-frequency: set maximum clock frequency, must be 830000
+ - spi-cpol and spi-cpha:

+
+See for more details:
+ Documentation/devicetree/bindings/spi/spi-bus.txt
+
+Note about max frequency:
+ Chip's max frequency, as specified in its datasheet, is 2Mhz. But a 600ns
+ delay is expected between the application of a logic LO to CS and the
+ application of SCLK, as also specified. And since the delay is not
+ implemented in the spi code, to satisfy it, SCLK's period should be at most
+ 2 * 600ns, so the max frequency should be 1 / (2 * 6e-7), which gives
+ roughly 830000Hz.

+Example:
