See RPi peripherals documentation, c. 6.2. https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2835/BCM2835-ARM-Peripherals.pdf Each output marked as GPCLK may be used in theory. Currently only GPIO4 and GPIO21 are supported by this project. In order to switch to GPIO21 please see instructions for Raspberry Pi 4, as pin 40 is preferred for this board.
