From 314413317b6d78cc76cd48f0296fde9fcfdec400 Mon Sep 17 00:00:00 2001 From: Judith Mendez Date: Fri, 11 Oct 2024 12:52:03 -0500 Subject: [PATCH] clocksource/drivers/timer-ti-dm: Don't fail probe if int not found Some timers may not have an interrupt routed to the A53 GIC, but the timer PWM functionality can still be used by Linux Kernel. Therefore, do not fail probe if interrupt is not found and ti,timer-pwm exists.
