On av very clean install of L4T 21.2, the make suddenly fails while compiling the dts files. The message is
arch/arm/boot/dts/tegra124.dtsi:1:41: fatal error: dt-bindings/gpio/tegra-gpio.h: No such file or directory
Actualy, the zImage file is ok, so it does not matter much. It happend when I edited the dts file tegra124-jetson_tk1-pm375-000-c00-00.dts which I manualy compile it into its dtb file.
The file tegra-gpio.h does exist in two places, both identical.
Why does not the dts/dtb compiler find it?
