* ST-Microelectronics SPI FSM Serial (NOR) Flash Controller
Required properties:
- - compatible : Should be "st,spi-fsm"
+ - compatible : "st,spi-fsm" is now DEPRECATED
+ Should be one of;
+ "st,stid127-spi-fsm"
+ "st,stih407-spi-fsm"
+ "st,stih416-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
+ - st,syscfg : Phandle to boot-device system configuration registers
Example:
spifsm: spifsm@fe902000{
- compatible = "st,spi-fsm";
+ compatible = "st,stih407-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";
};

This driver now obtains platform information via DT matching, which requires a compatible string per platform. This change introduces the new specific strings and deprecates the old generic one. We also take out all of the old, unused properties which are no longer required.
