Subject: [PATCH net-next v3 5/5] ARM: dts: r9a06g032: describe GMAC1

From: Clément Léger <[email protected]>

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.

The surrounding "soc" node already specifies the interrupt parent,
so there is no need to repeat that. I could fix that while applying
to renesas-devel for v6.10, but it looks like there will be a v4 for
the rest of the series anyway?

The rest LGTM, so with the above fixed:

Indeed there will be a v4 so I'll fix it.
