So far, there are at least 3 different versions with 3 combinations of 2 different HW changes (PCIe lane layout, and SD card GPIO assignments). I suspect we'll want this file to be tegra186-p2771-0000-NNN.dts where NNN is the version number from the EEPROM (which is 000 for the first version, 300 for the version that introduces the first change, and 500 for the version that introduces the second change). > diff --git a/arch/arm64/boot/dts/nvidia/tegra186-p2771-0000.dts b/arch/arm64/boot/dts/nvidia/tegra186-p2771-0000.dts > +#include "tegra186-p3310.dtsi" > + > +/ { > + model = "NVIDIA Tegra186 P2771-0000 Board"; > + compatible = "nvidia,p2771-0000", "nvidia,tegra186"; Do we need to propagate the "nvidia,p3310" entry from the included CVM DT? It'd be nice if we could write: /prepend/ compatible = "nvidia,p2771-0000"; ... and have that happen automatically. -- 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
