* ST-Microelectronics SPI FSM Serial (NOR) Flash Controller



Required properties:

  - compatible : Should be "st,spi-fsm"

  - reg        : Contains register's location and length.

  - 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>;

		status = "okay";

	};
