From: Michael Shych <michaelsh@xxxxxxxxxxxx> This patchset introduces watchdog driver for a various range of Mellanox Ethernet and Infiniband switch systems. Mellanox watchdog device is implemented in programmable logic device. There are 2 types of HW watchdog implementations with different capabilities. This mlx-wdt driver supports both HW watchdog implementations. Mellanox system can have 2 watchdogs: main and auxiliary. Main and auxiliary watchdog devices can be enabled together on the same system. There are several actions that can be defined in the watchdog: system reset, start fans on full speed and increase register counter.
