Subject: [PATCH 09/10] ARM: dts: omap4: convert IOMMUs to use ti-sysc
Date: Wed, 28 Aug 2019 10:56:43 +0300	[thread overview]
Message-ID: <20190828075644.4493-10-t-kristo@ti.com> (raw)
In-Reply-To: <20190828075644.4493-1-t-kristo@ti.com>

Convert omap4 IOMMUs to use ti-sysc instead of legacy omap-hwmod based
implementation. Enable the IOMMUs also while doing this.
