Subject: [PATCH v5 8/9] ARM: dts: r8a7790: add iommus to dmac0 and dmac1
Date: Tue, 8 Mar 2016 03:42:53 +0100 [thread overview]
Message-ID: <1457404974-1800-9-git-send-email-niklas.soderlund+renesas@ragnatech.se> (raw)
In-Reply-To: <1457404974-1800-1-git-send-email-niklas.soderlund+renesas-1zkq55x86MTxsAP9Fp7wbw@public.gmane.org>
A unconfirmed hardware bug prevents channel 0 and 15 to be used by the
DMAC together with the IPMMU. The DMAC driver will disable the channels
reducing the effective number of channels to 14 per DMAC.
