Yes , that is the driver by Nicolas Saenz which will be  triggered by =
bcm2711-rpi-4-b.dtb  reset function ,
in his whole related patchset bcm2711-rpi-4-b.dts is patched with the =
reset-function.

bcm2711-rpi-4-b.dts in D26853 is the professional version of it :-)... =
Ha Ha .. just kidding...

we really should control bcm2711-rpi-4-b.dts by ourselves,
It=E2=80=99s not the first time that strange versions of that file are =
breaking drivers,
we had that with genet(and pcie) in the past IIRC(Rob and me have talked =
about it).

Andy, thanks for testing so extensively useful !
