Subject: [PATCH v3 2/4] ARM: phytec-som-imx6: remove needles enet refclk setup
Date: Wed,  7 Jun 2017 12:34:20 +0200	[thread overview]
Message-ID: <20170607103422.4673-3-m.grzeschik@pengutronix.de> (raw)
In-Reply-To: <20170607103422.4673-1-m.grzeschik@pengutronix.de>

All REF_CLK output setup now is generically prepared for imx6ul. The
handling of the ENET_CLK_SEL (gpr[13]|gpr[14]) bits is not necessary, as
0 is their reset value.
