Subject: [PATCH 1/3] ethoc: Write bus addresses to registers
Date: Tue, 18 May 2010 07:39:24 +0200 [thread overview]
Message-ID: <1274161166-18521-2-git-send-email-jonas@southpole.se> (raw)
In-Reply-To: <1274161166-18521-1-git-send-email-jonas@southpole.se>
The ethoc driver should be writing bus addresses to the ethoc registers, not
virtual addresses.
Also, use bus_to_virt instead of phys_to_virt to make this explicit.
