From 2b69a67389fc43d7e16ef8c31d2a8845572acff6 Mon Sep 17 00:00:00 2001 From: Marek Behún Date: Tue, 24 Apr 2018 17:21:30 +0200 Subject: watchdog: Add support for Armada 37xx CPU watchdog This adds support for the CPU watchdog found on Marvell Armada 37xx SoCs. There are 4 counters which can be set as CPU watchdog counters. This driver uses the second counter (ID 1, counting from 0) (Marvell's Linux also uses second counter by default). In the future it could be adapted to use other counters, with definition in the device tree.
