From 15966a2a76f57ee45479cc3e7d28dd105f09260a Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Wed, 6 May 2015 01:09:49 +0200 Subject: [PATCH] net: dsa: Converting remaining registers to mnemonics Use defines for registers, shifts and bits in the remaining register accesses in the individual drivers, in order to aid readability.
