From 0490cab58407afc23df4fbc05204c23395efd3fe Mon Sep 17 00:00:00 2001 From: Thomas Schaefer Date: Thu, 8 Aug 2019 16:00:30 +0800 Subject: [PATCH] armv8: ls1028a: configure PMU's PCTBENR to enable WDT The SP805-WDT module on LS1028A requires configuration of PMU's PCTBENR register to enable watchdog counter decrement and reset signal generation. The watchdog clock needs to be enabled first.
