I'll wait until the clock driver stuff is finalized and merged, then apply this on top. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Actually, I can't apply this yet, since it relies on the file <dt-bindings/clock/tegra124-car.h>, which is being added for 3.13 in a patch in the clock tree. This will have to wait until v3.13-rc1 or later. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I've applied this to Tegra's for-3.14/dt branch, with one minor fixup to add a unit address to /clocks/clock in tegra124-venice2.dts. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

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. --- arch/arm/boot/dts/tegra124-venice2.dts | 13 +++++++++++++ arch/arm/boot/dts/tegra124.dtsi | 16 ++++++++++++++++ 2 files changed, 29 insertions(+)
