+Required properties:
+- compatible : "nuvoton,npcm750-reset" for NPCM7XX BMC

+- #reset-cells: must be set to 2
+
+Optional property:
+- nuvoton,sw-reset-number - Contains the software reset number to restart the SoC.
+ NPCM7xx contain four software reset that represent numbers 1 to 4.
+
+ If 'nuvoton,sw-reset-number' is not specfied software reset is disabled.
+
+Example:
+ rstc: rstc@f0801000 {
+ compatible = "nuvoton,npcm750-reset";
+ reg = <0xf0801000 0x70>;
+ #reset-cells = <2>;
+ nuvoton,sw-reset-number = <2>;
+ };
+
+Specifying reset lines connected to IP NPCM7XX modules

+
+ spi0: spi@..... {
+ ...
+ resets = <&rstc NPCM7XX_RESET_IPSRST2 NPCM7XX_RESET_PSPI1>;
