Subject: [PATCH 19/22] msm: iommu: Add bus clocks to platform data
Date: Thu, 16 Dec 2010 16:50:03 -0800 [thread overview]
Message-ID: <1292547006-19741-20-git-send-email-sboyd@codeaurora.org> (raw)
In-Reply-To: <1292547006-19741-1-git-send-email-sboyd@codeaurora.org>
From: Stepan Moskovchenko <stepanm@codeaurora.org>
Add the IOMMU bus clock and the IOMMU bus interconnect
clocks to the platform data for an IOMMU device. These
clocks are needed to access the IOMMU registers.
