Subject: [patch 3.8-rc2] drivers/net/phy/micrel.c
From: David J. Choi <david.choi@...rel.com>
Summary of changes:
This patch is primarily intended to cover more Ethernet phys from Micrel Inc. Additionally it
.supports ksz8081/91, ksz8061, ksz9051 device.
.changes KSxxx to KSZxxx for unified naming convention. For example, change KS8737 to KSZ8737.
.changes 9021 to 90x1 for commonly used names between 9021 and 9031 device, as this patch includes
KSZ9031 which belongs to same family as 9021.
2 files(include/linux/micrel_phy.h, drivers/net/phy/micrel.c) are changed.
