Subject: [RFC PATCH v11 4/9] clocksource: Add clocksource id for arm arch counter
Date: Tue, 21 Apr 2020 11:22:59 +0800	[thread overview]
Message-ID: <20200421032304.26300-5-jianyong.wu@arm.com> (raw)
In-Reply-To: <20200421032304.26300-1-jianyong.wu@arm.com>

Add clocksource id for arm arch counter to let it be identified easily and
elegantly in ptp_kvm implementation for arm.
