Subject: [PATCH/RFC 03/03] ARM: shmobile: r8a7795: Tie in IPMMU with SYS-DMAC0
Date: Tue, 15 Dec 2015 13:27:00 +0000 [thread overview]
Message-ID: <20151215132700.15356.86856.sendpatchset@little-apple> (raw)
From: Magnus Damm <damm+renesas@opensource.se>
Hook up IPMMU-MM and IPMMU-DS0 to the r8a7795 DTS and
make sure the SYS-DMAC0 is connected to IPMMU-DS0.
The DT binding for the IPMMU will change.
Not for upstream merge.
