Subject: [PATCH v3 08/17] clocksource/arm_arch_timer: Advertise 56bit timer to the core code
Date: Sun, 10 Oct 2021 12:42:57 +0100 [thread overview]
Message-ID: <20211010114306.2910453-9-maz@kernel.org> (raw)
In-Reply-To: <20211010114306.2910453-1-maz@kernel.org>
Proudly tell the code code that we have a timer able to handle
56 bits deltas.
