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’s 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 !
