From e78adcfe48daf7b322c09aa19930b8051adf04c8 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Wed, 6 Feb 2019 11:32:35 +0800 Subject: [PATCH] ARM: dts: sun9i: Add GMAC clock node The A80 has the same DWMAC hardware as on earlier Allwinner SoCs. The accompanying GMAC clock register has been moved into the "System Control" area. Add a clock node for it.
