* 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";
};
