From 1ac0e845c10685f3643fe81a08c13be4b9416bce Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Sat, 10 Aug 2013 18:52:17 +0200 Subject: [PATCH] dma: mmp_pdma: fix maximum transfer length There's no reason for limiting the maximum transfer length to 0x1000. Take the actual bit mask instead; the PDMA is able to transfer chunks of up to SZ_8K - 1.
