Subject: [PATCH 03/21] dt-binding: memory: mediatek: Add domain definition
Date: Sat, 11 Jul 2020 14:48:28 +0800	[thread overview]
Message-ID: <20200711064846.16007-4-yong.wu@mediatek.com> (raw)
In-Reply-To: <20200711064846.16007-1-yong.wu@mediatek.com>

In the latest SoC, there are several HW IP require a sepecial iova
range, mainly CCU and VPU has this requirement. Take CCU as a example,
CCU require its iova locate in the range(0x4000_0000 ~ 0x43ff_ffff).

In this patch we add a domain definition for the special port. This is
a preparing patch for multi-domain support.
