DT, as a type of firmware node, needs to implement firmware node
interfaces 'struct fwnode_operations' defined in fwnode.h.
so it includes fwnode.h and knows everything of fwnode.h
A)
diff --git a/include/linux/of.h b/include/linux/of.h
#define MAX_PHANDLE_ARGS 16
struct of_phandle_args {
struct device_node *np;
int args_count;
uint32_t args[MAX_PHANDLE_ARGS];
};
+static_assert(NR_FWNODE_REFERENCE_ARGS == MAX_PHANDLE_ARGS);
B)
diff --git a/include/linux/of.h b/include/linux/of.h
-#define MAX_PHANDLE_ARGS 16
+#define MAX_PHANDLE_ARGS NR_FWNODE_REFERENCE_ARGS
you like solution A), right ?
