[PATCH] ARM: dts: am43xx: fix edma memcpy channel allocation

From: Tero Kristo <hidden>
Date: 2016-03-14 09:01:50
Also in: linux-devicetree, linux-omap
Subsystem: the rest · Maintainer: Linus Torvalds

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.
