- reg : specifies physical base address and size of the register.
- #reset-cells: must be set to 2
- syscon: a phandle to access GCR registers.
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.
+ NPCM7xx and NPCM8xx contain four software reset that represent numbers 1 to 4.
