Message-Id: <1427940400-12434-12-git-send-email-andrew@lunn.ch>

Cc: netdev@...r.kernel.org, Andrew Lunn <andrew@...n.ch>
Subject: [PATCHv2 11/12] net: dsa: Use mnemonics rather than register numbers
Rather than refer to registers by number, define mnemonics. Also
define mnemonics for the commonly used bits within the registers.
