Subject: [PATCH v14 06/10] clocksource: Add clocksource id for arm arch counter
Date: Fri,  4 Sep 2020 17:27:40 +0800	[thread overview]
Message-ID: <20200904092744.167655-7-jianyong.wu@arm.com> (raw)
In-Reply-To: <20200904092744.167655-1-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.
