+Device tree source (DTS) decompiler on Android device.
+
+This is alternative to dtdiff, which only support bash.
+
+How to use for rust_test
+========================
+
+Following dependencies are needed in addition to libdts.
+
+```
+rust_test {
+  ...
+  data_bins: ["dtc_static"],
+  compile_multilib: "first",
