Dtb for bbblue not configuring pru pins


People are trying to use bbblue and are having problems using kernel 5.10
The pru pins is not enabled and even loading the overlays - or aio or pru-rpproc there is no output on the expected pins(servo rails).
With 4.19-ti kernel and rpproc-4.19 is working fine.
How can we enable the pru out pins o. 5.10 version?
