Subject: [PATCH 1/7] sky2: dont set bogus bit in PHY register
Date: Thu, 24 May 2007 15:22:43 -0700	[thread overview]
Message-ID: <20070524222538.375321658@linux-foundation.org> (raw)
In-Reply-To: 20070524222242.555399884@linux-foundation.org

[-- Attachment #1: sky2-gphy-ctrl.patch --]
[-- Type: text/plain, Size: 2242 bytes --]

This code inherited from the sk98lin driver is incorrect on the Yukon2.
The GPHY_CTRL register values are specific to the internal PHY of the chip
and the values used were leftovers.
Driver was setting bit 13 which is now the INT polarity for the PHY!
