From 2156016294c7cb005bba3d8b7c7f13bc09d7824c Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Wed, 14 Apr 2021 09:18:21 +0200 Subject: [PATCH] timer: mpc83xx_timer: fix build with CONFIG_{HW_, }WATCHDOG The code, which is likely copied from arch/powerpc/lib/interrupts.c, lacks a fallback definition of CONFIG_SYS_WATCHDOG_FREQ and refers to a non-existing timestamp variable - obviously priv->timestamp is meant.
