Date: Wed, 12 Jul 2017 18:28:10 +0200
From: Alexander Dahl <ada@...rsis.com>
To: linux-kernel@...r.kernel.org
Cc: Nicolas Ferre <nicolas.ferre@...rochip.com>,
netdev@...r.kernel.org, linux-arm-kernel@...ts.infradead.org
Subject: [RFC 1/3] net: macb: Add register descriptions
Analog to the already present long register names for GEM, add those for
MACB. Taken from the AT91SAM9G20 complete datasheet.
