-Nuvoton NPCM Reset controller
-
-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 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 specified 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
-======================================================
-example:
-
- spi0: spi@..... {
- ...
- resets = <&rstc NPCM7XX_RESET_IPSRST2 NPCM7XX_RESET_PSPI1>;
- ...
- };
-
-The index could be found in <dt-bindings/reset/nuvoton,npcm7xx-reset.h>.
