Subject: [PATCH v2 08/16] clocksource/arm_arch_timer: Advertise 56bit timer to the core code
Date: Wed, 22 Sep 2021 22:19:33 +0100	[thread overview]
Message-ID: <20210922211941.2756270-9-maz@kernel.org> (raw)
In-Reply-To: <20210922211941.2756270-1-maz@kernel.org>

Proudly tell the code code that we have a timer able to handle
56 bits deltas.
