Subject: [PATCH v3 10/17] clocksource/arm_arch_timer: Remove any trace of the TVAL programming interface
Date: Sun, 10 Oct 2021 12:42:59 +0100	[thread overview]
Message-ID: <20211010114306.2910453-11-maz@kernel.org> (raw)
In-Reply-To: <20211010114306.2910453-1-maz@kernel.org>

TVAL usage is now long gone, get rid of the leftovers.
