Subject: [PATCH 14/23] OMAPDSS: configure WB fifo thresholds
Date: Wed, 09 Dec 2015 15:59:42 +0000	[thread overview]
Message-ID: <1449676791-26304-15-git-send-email-tomi.valkeinen@ti.com> (raw)

Fifo thresholds for all pipelines are set in dispc_init_fifos(), but we
are missing it for WB pipeline. Add that.
