+# Input filter hack to trick Doxygen into thinking that a series
+# header is in a separate namespace. This is necessary because Doxygen
+# doesn't know how to cope with two data structures with the same name
+# in different places in the project. (We do that all the time,
+# e.g. for foo_reg_map structs.)
+#
+# E.g., an STM32F1 header gets transformed into:
+#
+# namespace stm32f1 {
+# <contents of header>
+# }
+
+BEGIN {
+    # For extracting series component from header FILENAME.
+    series_regex = "/stm32[flw][0-9]*/";
+    # Holds header FILENAME. Cargo-culted; not sure why it's necessary.
+    f = "";
+    # Holds series component.
+    series = "";
+}
+{
+    if (f != FILENAME) {
+        f = FILENAME;
+        match(f, series_regex);
+        series = substr(f, RSTART + 1, RLENGTH - 2);
+        printf("namespace %s {\n", series);
+    }
+    print;

+END {
