Subject: [PATCH v8 09/14] dt-bindings: iommu/rockchip: Add clock property
Date: Fri, 23 Mar 2018 15:38:09 +0800	[thread overview]
Message-ID: <20180323073814.5802-10-jeffy.chen@rock-chips.com> (raw)
In-Reply-To: <20180323073814.5802-1-jeffy.chen-TNX95d0MmH7DzftRWevZcw@public.gmane.org>

Add clock property, since we are going to control clocks in rockchip
iommu driver.
