From the Altera SoC Quick Start Guide for ADRV9371, your website provides socfpga_arria_socdk_adrv9371.dts. I want to transfer this .dts to .dtb, but "dtc -I dts -O dtb -o socfpga_arria10_socdk.dtb socfpga_arria10_socdk_adrv9371.dts" doesn't work, which gives errors:
Error: socfpga_arria10_socdk_adrv9371.dts:2.1-9 syntax error
FATAL ERROR: Unable to parse input tree
The socfpga_arria10_socdk_adrv9371.dts requires socfpga_arria10_socdk.dtsi and ad9528.h and I've these files along with .dts in the same directory. What did I do wrong?
