[PATCH] phy/micrel: Add suspend/resume support to Micrel PHYs

From: Nicolas Ferre <hidden>
Date: 2013-09-19 17:39:33
Also in: linux-arm-kernel, lkml
Subsystem: ethernet phy library, networking drivers, the rest · Maintainers: Andrew Lunn, Heiner Kallweit, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

From: Patrice Vilchez <redacted>

All supported Micrel PHYs implement the standard "power down" bit 11 of BMCR,
so this patch adds support using the generic genphy_{suspend,resume} functions.
