Subject: [PATCH 6/8] [Blackfin] EMAC driver: add power down mode
Date: Wed, 30 Jan 2008 16:52:26 +0800	[thread overview]
Message-ID: <1201683148-23931-7-git-send-email-bryan.wu@analog.com> (raw)
In-Reply-To: <1201683148-23931-1-git-send-email-bryan.wu@analog.com>

From: Vitja Makarov <vitja.makarov@gmail.com>

This patch puts phy in power-down mode when interface is down.
Also we should think about energy detect power-down mode, that will
decrease power consumption when no link.
