| 3 | Required properties: |
| 4 | - compatible : Should be "st,spi-fsm" |
| 5 | - reg : Contains register's location and length. |
| 6 | - reg-names : Should contain the reg names "spi-fsm" |
| 7 | - interrupts : The interrupt number |
| 8 | - pinctrl-0 : Standard Pinctrl phandle (see: pinctrl/pinctrl-bindings.txt) |
| 9 | |
| 10 | Optional properties: |
| 11 | - st,syscfg : Phandle to boot-device system configuration registers |
| 12 | - st,boot-device-reg : Address of the aforementioned boot-device register(s) |
| 13 | - st,boot-device-spi : Expected boot-device value if booted via this device |
| 14 | |
| 15 | Example: |
| 16 | spifsm: spifsm@fe902000{ |
| 17 | compatible = "st,spi-fsm"; |
| 18 | reg = <0xfe902000 0x1000>; |
| 19 | reg-names = "spi-fsm"; |
| 20 | pinctrl-0 = <&pinctrl_fsm>; |
| 21 | st,syscfg = <&syscfg_rear>; |
| 22 | st,boot-device-reg = <0x958>; |
| 23 | st,boot-device-spi = <0x1a>; |
| 24 | }; |
