Subject: [PATCH 29/42] ARM: i.MX8M: Add some lowlevel clock functions
Date: Mon, 17 Feb 2020 13:46:10 +0100	[thread overview]
Message-ID: <20200217124623.14520-30-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20200217124623.14520-1-s.hauer@pengutronix.de>

U-Boot has some lowlevel clock functions which take a clock slice index
as argument. Add them for barebox as well to make the code better
comparable to U-Boot.
