Subject: [PATCH v2 1/3] ARM: i.MX: setup ENET_TX_CLK_DIR in imx6_init for every imx6ul
Date: Fri,  2 Jun 2017 15:18:06 +0200	[thread overview]
Message-ID: <20170602131808.18781-2-m.grzeschik@pengutronix.de> (raw)
In-Reply-To: <20170602131808.18781-1-m.grzeschik@pengutronix.de>

We generically enable the output of ENET_TX_CLK.
It will be output if ENET_REF_CLK is selected.
