Hi,

With new dtc+cpp feature, we can get rid of magic numbers in dts*
files. To get rid of Tegra clock magic number, the following patches
were created with a script run as below. This can be applied for
Tegra114 clock as well.

for x in 20 30; do
    cat drivers/clk/tegra/clk-tegra$x.c | enum2define.py \
    	> arch/arm/boot/dts/tegra$x-car.h 2>/tmp/tegra$x-car.sed
    sed -i -f /tmp/tegra$x-car.sed \
    	Documentation/devicetree/bindings/clock/nvidia\,tegra$x-car.txt \
	arch/arm/boot/dts/*
done

We plan to share those DT header files with kernel source later[1].

This series depends on:
