From 1adf02ffad449ea955e21393e05b0e45ef2c16a4 Mon Sep 17 00:00:00 2001 From: Vasanthakumar Thiagarajan Date: Thu, 15 Apr 2010 17:38:24 -0400 Subject: [PATCH] ath9k_hw: Add hw cap flag for EDMA for the AR9003 family AR9003 supports extended DMA (EDMA), this comes with some bells and whistles on top of the legacy DMA that we are used to. Mark AR9003 and later chips EDMA capable. Signed-off-by: Vasanthakumar Thiagarajan Signed-off-by: John W.
