From 946af15b9614f49f3a28b62d516867031428d561 Mon Sep 17 00:00:00 2001 From: George Cherian Date: Mon, 9 Oct 2023 10:10:37 +0530 Subject: [PATCH] drivers: watchdog: marvell_gti: Program the max_hw_heartbeat_ms Program the max_hw_heartbeat_ms value so that the watchdog_pretimeout worker is activated. This kernel worker thread makes sure to ping the watchdog in case the userspace is unable to do so. This kernel worker ping will be done only till the full watchdog timeout there by maintaining the watchdog functionality in case of a real hang.
