What about: ===== Create a header file to define the clock IDs used by the Tegra20 clock binding. Remove the list of definitions from the binding documentation, and refer the reader to the header file. This will allow the same header to be used by both device tree files, and drivers implementing this binding, which guarantees that the two stay in sync. This also makes device trees more readable by using names instead of magic numbers. ===== I'm not sure exactly how these patches will get merged. For you reference, I anticipate one of two things happening: 1) * Patches 1, 3, 5 get put into a topic branch, and merged into both the clk tree and the Tegra tree. * Patches 2, 4, 6 get merged into the Tegra tree. * The patches you're going to create for the drivers/clk code get merged into Mike's clk tree 2) * Mike ack's the patches you're going to create for the drivers/clk code. * Everything gets merged through the Tegra tree. This shouldn't impact you much, but just be aware that the drivers/clk changes you create shouldn't depend on anything beyond patches 1, 3, 5 here and 3.10-rc1, then I can work out the merging with Mike without any constraints. > diff --git a/Documentation/devicetree/bindings/clock/nvidia,tegra20-car.txt b/Documentation/devicetree/bindings/clock/nvidia,tegra20-car.txt > This binding uses the common clock binding: > Documentation/devicetree/bindings/clock/clock-bindings.txt > > +You can find the actual assignment in "dt-bindings/clk/tegra20-car.h" Can you move this text down into the description of clock-cells, i.e. where you removed the original list of IDs? That'll keep the text in the place it's most useful. I would also like to explicitly mention "include file" and use <> rather than "", since that matches the syntax that should be used in .dts files, i.e.: ===== - #clock-cells : Should be 1. In clock consumers, this cell represents the clock ID exposed by the CAR. The assignments may be found in header file <dt-bindings/clk/tegra20-car.h>. ===== Similar comments for patches 3 and 5. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
