The routing paths listed are entries connecting the digital and analog side of the audio codec together. Due to how device tree works, these must be copied over to each board device tree, in addition to any board level routes. The oversampling rate is set to 128, so that when playing back 192 kHz audio samples, the MCLK runs at the same rate as the module clock, at 24.576 MHz. The user manual suggests using different oversampling rates for different sample rates, but that's not possible without a platform-specific machine driver.
