The system reboot on the cameo-rtl9302c (and presumably many other boards based on the realtek reference design) is connected via the switch reset register (RST_GLB_CTRL_0). Because the switch register block encompasses a number of functions that would normally be separate perhipherals I've represented it as a syscon node. Right now the only peripheral I've added is the reset (using syscon-reboot). The binding and syscon node will be expanded in the future to add some additional functions (e.g. I2C, GPIO, MDIO).
