Subject: [PATCH 07/13] clocksource/arm_arch_timer: Advertise 56bit timer to the core code
Date: Mon, 9 Aug 2021 16:26:45 +0100 [thread overview]
Message-ID: <20210809152651.2297337-8-maz@kernel.org> (raw)
In-Reply-To: <20210809152651.2297337-1-maz@kernel.org>
Proudly tell the code code that we have a timer able to handle
56 bits deltas.
