From d86ad463d6706d35167418660ae3293207ee9d1c Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 28 May 2020 08:54:53 -0700 Subject: ARM: OMAP2+: Fix regression for using local timer on non-SMP SoCs On am437x we use also an ARM timer in addition to the dmtimer. As am437x is not an SMP SoC, we need tick_broadcast() implemented. With the recent dmtimer changes, Arnd started to see link failures for non-SMP am437x configuration: kernel/time/tick-broadcast.o: in function `tick_device_uses_broadcast': tick-broadcast.c:(.text+0x130): undefined reference to `tick_broadcast' Let's fix the issue by reverting dmtimer related changes that started building timer.c only for CONFIG_SOC_HAS_REALTIME_COUNTER. We still always need timer.c built-in for omap5 and dra7 for timer_probe(). And let's also move am437x tick_broadcast() to board-generic.c as that's where we now call timer_probe() for am437x. This way we avoid adding back more ifdefs to timer.c.
