  • reg-names : Should contain the reg names “spi-fsm”
  • interrupts : The interrupt number
  • pinctrl-0 : Standard Pinctrl phandle (see: pinctrl/pinctrl-bindings.txt)

Optional properties:

  • st,syscfg : Phandle to boot-device system configuration registers
  • st,boot-device-reg : Address of the aforementioned boot-device register(s)
  • st,boot-device-spi : Expected boot-device value if booted via this device

Example:
spifsm: spifsm@fe902000{
compatible = “st,spi-fsm”;
reg = <0xfe902000 0x1000>;
reg-names = “spi-fsm”;
pinctrl-0 = <&pinctrl_fsm>;
st,syscfg = <&syscfg_rear>;
st,boot-device-reg = <0x958>;
st,boot-device-spi = <0x1a>;
};
