Subject: [PATCH 08/10] ARM: dts: dra74x: convert IOMMUs to use ti-sysc
Date: Wed, 28 Aug 2019 10:56:42 +0300	[thread overview]
Message-ID: <20190828075644.4493-9-t-kristo@ti.com> (raw)
In-Reply-To: <20190828075644.4493-1-t-kristo@ti.com>

Convert dra74x IOMMUs to use ti-sysc instead of legacy omap-hwmod based
implementation. Enable the IOMMUs also while doing this.
