+* Nuvoton FLASH Interface Unit (FIU) SPI Controller
+
+NPCM FIU supports single, dual and quad communication interface.
+
+The NPCM7XX supports three FIU modules,
+FIU0 and FIUx supports two chip selects,
+FIU3 support four chip select.
+
+Required properties:
+  - compatible : "nuvoton,npcm750-fiu" for the NPCM7XX BMC
+  - #address-cells : should be 1.
+  - #size-cells : should be 0.

+  - reg-names: Should contain the reg names "control" and "memory"
+  - clocks : phandle of FIU reference clock.
+
+Required properties in case the pins can be muxed:
+  - pinctrl-names : a pinctrl state named "default" must be defined.
+  - pinctrl-0 : phandle referencing pin configuration of the device.
+
+Optional property:
+  - nuvoton,spix-mode: enable spix-mode for an expansion bus to an ASIC or CPLD.
+
+Aliases:
+- All the FIU controller nodes should be represented in the aliases node using
+  the following format 'fiu{n}' where n is a unique number for the alias.
+  In the NPCM7XX BMC:
+  		fiu0 represent fiu 0 controller
+  		fiu1 represent fiu 3 controller
+  		fiu2 represent fiu x controller
