    +Nuvoton NPCM Reset controller
    +
    +In the NPCM Reset controller boot the USB PHY, USB host
    +and USB device initialize.
    +
    +Required properties:
    +- compatible : "nuvoton,npcm750-reset" for NPCM7XX BMC
    +- reg : specifies physical base address and size of the register.
    +- #reset-cells: must be set to 1
    +
    +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 = <1>;
    + nuvoton,sw-reset-number = <2>;
    + };
    +
    +Specifying reset lines connected to IP NPCM7XX modules
    +======================================================
    +example:
    +
    + spi0: spi@..... {
    + ...
    + resets = <&rstc NPCM7XX_RESET_PSPI1>;
    + ...
    + };
    +
    +The index could be found in <dt-bindings/reset/nuvoton,npcm7xx-reset.h>.
