Subject: [PATCH net-next v4 5/5] ARM: dts: r9a06g032: describe GMAC1

From: Clément Léger <clement.leger@...tlin.com>

The r9a06g032 SoC of the RZ/N1 family features two GMAC devices named
GMAC1/2, that are based on Synopsys cores. GMAC1 is connected to a
RGMII/RMII converter that is already described in this device tree.
