Subject: [PATCH] arm64: dts: renesas: r8a7795: Add IPMMU-PV1 device node
Date: Tue,  6 Mar 2018 10:34:30 +0100	[thread overview]
Message-ID: <20180306093430.12486-1-horms+renesas@verge.net.au> (raw)

Add r8a7795 IPMMU-PV1 and keep it disabled by default.

This device is not present in r8a7795 ES1.x and
is removed from the DT of those SoCs.

This corrects an omission in
3b7e7848f0e8 ("arm64: dts: renesas: r8a7795: Add IPMMU device nodes")

This does not have any runtime effect.
