From 75ae118a0028810f93a746c25f4bb018fb044323 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Sat, 26 Nov 2011 14:36:19 +0200 Subject: OMAPDSS: APPLY: add dss_setup_fifos Currently fifo threshold configuration is done per overlay or per manager. However, when a fifo size configuration is added, we need to always configure the thresholds for all overlays. This patch prepares for that by changing the fifo threshold configuration to always handle all overlays.
