Subject: [PATCH 9/9] clk: i.MX7: setup ethernet clocks
Date: Mon,  6 Feb 2017 07:50:57 +0100	[thread overview]
Message-ID: <20170206065057.19483-10-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20170206065057.19483-1-s.hauer@pengutronix.de>

Reparent ethernet clocks so that they can be used by the
fec driver. The values are the same as U-Boot uses.
