From 2a4056a759e26745f3a19431f5428c581fd8f347 Mon Sep 17 00:00:00 2001 From: Biju Das Date: Tue, 24 Jul 2018 16:47:18 +0100 Subject: [PATCH 01/21] soc: renesas: Identify RZ/G2M This patch adds support for identifying the RZ/G2M (r8a774a1) SoC. It corrects the original RZ/G SoC family name to RZ/G1 and also adds support for the new RZ/G2 SoC family.
