Subject: [PATCH v2 4/6] clocksource: Change CPU hotplug priority of exynos_mct driver
Date: Mon, 15 Oct 2018 14:31:10 +0200	[thread overview]
Message-ID: <20181015123112.9379-5-m.szyprowski@samsung.com> (raw)
In-Reply-To: <20181015123112.9379-1-m.szyprowski@samsung.com>

Exynos Multi-Core Timer driver (exynos_mct) must be started before
ARM Architected Timers (arch_timer), because both timers share common
hardware block and turning on MCT is needed to get ARM Architected
Timer working properly.
