From d4238aa458b8c3e64d6f124aafa5c230cae31d6a Mon Sep 17 00:00:00 2001 From: Andrew Jeffery Date: Wed, 20 Sep 2017 15:00:20 +0930 Subject: watchdog: aspeed: Move init to arch_initcall Probing at device_initcall time lead to perverse cases where the watchdog was probed after, say, I2C devices, which then leaves a potentially running watchdog at the mercy of I2C device behaviour and bus conditions. Load the watchdog driver early to ensure that the kernel is patting it well before initialising peripherals.
