Subject: [PATCH 10/14] clk: Add lock to different clock types
Date: Tue, 18 May 2021 13:49:25 +0200	[thread overview]
Message-ID: <20210518114929.12964-11-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20210518114929.12964-1-s.hauer@pengutronix.de>

The different clock types in Linux have a spinlock_t *lock field. Add
the same in barebox to ease code porting from Linux.
