Subject: [PATCH] arm64: dts: renesas: r8a77990: Attach the SYS-DMAC to the IPMMU
Date: Mon, 17 Sep 2018 17:19:49 +0900 [thread overview]
Message-ID: <153717238926.32742.16468076576808713610.sendpatchset@octo> (raw)
From: Magnus Damm <damm@opensource.se>
For R-Car E3 hook up SYS-DMAC0, SYS-DMAC1 and SYS-DMAC2 to
IPMMU-DS0 and IPMMU-DS1 in same way as for R-Car H3.
This follows the R-Car Gen3 Rev.1.00 (April 2018) datasheet.
