+* 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";
+ };
