I am working with the PRU on the 3.14 series kernel.
There is no cape manager, and I want to employ the proper technique for
muxing a PRU pin.

For example, the file "am335x-bone-common-pinmux.dtsi" contains this
definition which
is the pin&mode that I want to activate:

P9_25_pruin_pin: pinmux_P9_25_pruin_pin {
   pinctrl-single,pins = <0x1ac  0x26>; };     /* Mode 6, Pull-Down,
RxActive */

How exactly would I make use of this?

If you're using RCN's kernels, the universal overlay should already be part of the default device tree, so you can just use the config-pin utility:

  config-pin P9.25 pruin
