Subject: [PATCH net-next 09/10] tg3: Bypass power source switching for 57765
Date: Wed, 20 Jan 2010 18:58:10 -0800 [thread overview]
Message-ID: <1264042691-28284-10-git-send-email-mcarlson@broadcom.com> (raw)
The 57765 repurposes all the GPIOs normally used to switch power sources
when configured as a NIC device. This patch changes the code to avoid
touching the GPIOs for this asic rev.
