3 This node is intended to allow SoC reset in case of software reset
6 The Keystone SoCs can contain up to 4 watchdog timers to reset
7 SoC. Each watchdog timer event input is connected to the Reset Mux
8 block. The Reset Mux block can be configured to cause reset or not.
10 Additionally soft or hard reset can be configured.

17 and the PCI-host bridges found on IBM Power4, Power5 and Power6-based
22 offered, so that the affected PCI device(s) are reset and put back
