+From e7759c44e0c20dd6b5a259300acdc7350ea6dd32 Mon Sep 17 00:00:00 2001
+From: Linus Walleij <linus.walleij@linaro.org>
+Date: Mon, 6 Nov 2017 21:27:34 +0100
+Subject: [PATCH 07/31] pinctrl: gemini: Fix GMAC groups
+
+The GMII groups need to be split across GMAC0 and GMAC1 since
+GMAC0 is always available but GMAC1 masks GPIO2 lines 0-7
+so we might want just one interface out.
