"pinmux helper" is a kernel module that exports control of the pinmux settings to the sysfs filesystem where they can be manipulated by user-mode programs after boot. This helper module is used extensively by the "universal" cape I created which enables most of the AM335x hardware modules and allows run-time switching of the pinmux values (via the pinmux helper) to select the desired pin function.
