Subject: [PATCH] ARM: tegra: add clock properties for devices of Tegra124
Message-ID: <1381218460-23123-1-git-send-email-josephl@nvidia.com>
To: linux-arm-kernel@lists.infradead.org
List-Id: linux-arm-kernel.lists.infradead.org

This patch adds clock properties for devices in the DT for basic support
of Tegra124 SoC.

Signed-off-by: Joseph Lo <josephl@nvidia.com>
---
This patch was based on the series of Tegra124 clock driver and the basic
support of Tegra124. It coulud be used to replace the "HACK" patch in the
basic support of Tegra124 series.
