0002 ---------------------------------------
0003
0004 Required properties:
0005 - compatible : "st,comms-ssc4-spi"
0006 - reg : Offset and length of the device's register set
0007 - interrupts : The interrupt specifier
0008 - clock-names : Must contain "ssc"
0009 - clocks : Must contain an entry for each name in clock-names
0010 See ../clk/*
0011 - pinctrl-names : Uses "default", can use "sleep" if provided
0012 See ../pinctrl/pinctrl-bindings.txt
0013
0014 Optional properties:
0015 - cs-gpios : List of GPIO chip selects
0016 See ../spi/spi-bus.txt
0017
0018 Child nodes represent devices on the SPI bus
0019 See ../spi/spi-bus.txt
