+description:
+  The STMicroelectronics Fast Sequence Mode (FSM) controller is a dedicated
+  hardware accelerator integrated in older STiH4xx/STiDxxx set-top box SoCs
+  (such as STiH407, STiH416, STiD127). It connects directly to a single
+  external serial flash device used as the primary boot device. The FSM
+  executes hard-coded or configurable instruction sequences in hardware,
+  providing low-latency reads suitable for execute-in-place (XIP) boot
+  and high read bandwidth.

-* 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>;

Applied to mtd/next, thanks!

[1/1] dt-bindings: mtd: st,spi-fsm: convert to DT schema
      commit: 90541270967837c996631faa94e43d465e2a20c7

Patche(s) should be available on mtd/linux.git and will be
part of the next PR (provided that no robot complains by then).

Kind regards,
Miquèl
