From d41676ddddef27224a398609d874055866694cfa Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Mon, 14 Mar 2016 11:01:50 +0200 Subject: [PATCH] ARM: dts: am43xx: fix edma memcpy channel allocation EDMA was allocating DMA channels 32 and 33 for memcpy usage, out of which channel 33 is actually used by DES crypto engine. This bad allocation of the channel causes a crash in the DES crypto engine, as the channel gets configured for memcpy usage instead of hardware <-> memory DMA. Fixed by allocating DMA channels 58 and 59 for memcpy usage (I2C0 RX/TX), which are not used by anybody.
