From 24cc8d284b57e83fa6f866431c750aa79406e3b2 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Tue, 29 Nov 2016 14:10:59 +0100 Subject: [PATCH] imageon: Increase RX DMA FIFO size Increase the RX DMA FIFO to be able to better compensate for momentarily memory bus contention. This has shown to resolve occasional overflows that would occur under high system memory load.
