Subject: [PATCH 4/6] ARM: dts: omap5: convert IOMMUs to use ti-sysc
Date: Thu, 12 Dec 2019 14:51:21 +0200	[thread overview]
Message-ID: <20191212125123.3465-5-t-kristo@ti.com> (raw)
In-Reply-To: <20191212125123.3465-1-t-kristo@ti.com>

Convert omap5 IOMMUs to use ti-sysc instead of legacy omap-hwmod based
implementation. Enable the IOMMUs also while doing this.
