From d29bf01941795891828bf671f74c3a4f6fc3517f Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 9 Apr 2012 22:53:21 +0200 Subject: dma/amba-pl08x: check for terminal count status only For some reason I can't figure out we're reading the PL080_INT_STATUS register instead of PL080_TC_STATUS when checking for the terminal count. The PL080_INT_STATUS is a logical OR between the error and terminal count status register and may not report what we want it to, especially if there is an error and a terminal count at the same time and the former is not lowered in time for the check in the TC register. Make sure we read what we're actually interested in.
