Dspi-st-ssc.txt1 STMicroelectronics SSC (SPI) Controller
2 ---------------------------------------
5 - compatible : "st,comms-ssc4-spi"
6 - reg : Offset and length of the device's register set
7 - interrupts : The interrupt specifier
8 - clock-names : Must contain "ssc"
9 - clocks : Must contain an entry for each name in clock-names
11 - pinctrl-names : Uses "default", can use "sleep" if provided
12 See ../pinctrl/pinctrl-bindings.txt
