I have verified experimentally that the gate for R_PIO exists and works, though. There are probably other gates there but I don't know their order right now and I don't have access to their peripherals on my board to test them. After some experiments and reviewing how this is organized on other sunxi SoCs, I couldn't actually find any way to disable clocks for R_PIO and they are working properly without doing anything so I assume they are connected straight to the 24Mhz oscillator for now.
