Yes and mainline as well : drivers/clk/meson/axg-audio.c

Basically this driver is creating bypass input clocks (audio_pclk, mst_in[0-9],
etc...) .

This allows to collect input clocks from DT (like any consumer should) will
keeping constant in the controller clock tree.

one input, the AO should have 3.
