This patch changes the ISA Kconfig option dependency of the WinSystems EBC-C384 watchdog timer driver to ISA_BUS_API, thus allowing it to build for X86_64 as it is expected to.

The primary function of the deadman timer (DMT) is to reset the processor in the event of a software malfunction. The DMT is a free-running instruction fetch timer, which is clocked whenever an instruction fetch occurs until a count match occurs. Instructions are not fetched when the processor is in sleep mode.

More details about the hardware specification of this device: ARM DEN0029B - Server Base System Architecture (SBSA) This driver can operate ARM SBSA Generic Watchdog as a single stage watchdog or a two stages watchdog, it's set up by the module parameter "action". In the single stage mode, when the timeout is reached, your system will be reset by WS1. The first signal (WS0) is ignored. In the two stages mode, when the timeout is reached, the first signal (WS0) will trigger panic. If the system is getting into trouble and cannot be reset by panic or restart properly by the kdump kernel(if supported), then the second stage (as long as the first stage) will be reached, system will be reset by WS1. This function can help administrator to backup the system context info by panic console output or kdump. This driver bases on linux kernel watchdog framework, so it can get timeout from module parameter and FDT at the driver init stage.
