Subject: [PATCH 1/3] time/sched_clock: Export sched_clock_register()
Date: Wed, 8 Feb 2023 17:48:02 +0800 [thread overview]
Message-ID: <20230208094813.20874-2-walter.chang@mediatek.com> (raw)
In-Reply-To: <20230208094813.20874-1-walter.chang@mediatek.com>
From: Chun-Hung Wu <chun-hung.wu@mediatek.com>
clocksource driver may use sched_clock_register()
to resigter itself as a sched_clock source.
Export it to support building such driver
as module, like timer-mediatek.c
