Date: Tue, 17 Apr 2007 11:06:36 -0700 From: divy@...lsio.com To: jeff@...zik.org Cc: netdev@...r.kernel.org, linux-kernel@...r.kernel.org, swise@...ngridcomputing.com Subject: [PATCH 2.6.21 2/2] cxgb3 - PHY interrupts and GPIO pins. From: Divy Le Ray <divy@...lsio.com> Remove assumption that PHY interrupts use GPIOs 3 and 5. Deal with PHY interrupts connected to any GPIO pins.
