Actually I generate "arch/arm/boot/dts/tegra{20,30}-car.h" by parsing
"enum tegra{20,30}_clk {..};" with a python script.
There could be the same kind of requirement from others that both
"dtsip" and "C-source" want to share the same header file. If we
consider that DT is the exact H/W description, C-source should be able
to include a DT header file.
For example, a C-header file for "enum tegra{20,30}_clk" should be
generated from "arch/arm/boot/dts/tegra{20,30}-car.h" at runtime, or
alternatively just "drivers/clk/tegra/clk-tegra{20,30}.c" can include
"arch/arm/boot/dts/tegra{20,30}-car.h"? The latter may be easier.
