[PATCH 12/65] OMAPDSS: separate FIFO threshold setup from ovl_setup

Tomi Valkeinen
2011-11-22T09:22:57Z

Overlay FIFO thresholds are configured with ovl_setup, with all the
other overlay attributes. This patch separates FIFO threshold setup so
that we can later configure FIFO thresholds only when needed.
