From 43c2ed8e9e2d285be49d7ea1afc05071d5d7b0f9 Mon Sep 17 00:00:00 2001 From: Sriram Date: Thu, 24 Sep 2009 19:15:18 +0000 Subject: [PATCH] TI Davinci EMAC: Fix in vector definition for EMAC_VERSION_2 In the emac_poll function when looking for interrupt status masks correct definition must be chosen based on EMAC_VERSION(the bit mask has changed from version 1 to version 2).
