Subject: [PATCH AUTOSEL 4.14 24/33] net: bcmgenet: Fix RGMII_MODE_EN value for GENET v1/2/3
Date: Sat, 26 Oct 2019 09:21:01 -0400	[thread overview]
Message-ID: <20191026132110.4026-24-sashal@kernel.org> (raw)
In-Reply-To: <20191026132110.4026-1-sashal@kernel.org>

From: Florian Fainelli <f.fainelli@gmail.com>

[ Upstream commit efb86fede98cdc70b674692ff617b1162f642c49 ]

The RGMII_MODE_EN bit value was 0 for GENET versions 1 through 3, and
became 6 for GENET v4 and above, account for that difference.

Fixes: aa09677cba42 ("net: bcmgenet: add MDIO routines")
