As this property is in the mpfs devicetree & I'll need to fix it, is this
patch targeted at 5.19? (I assume given the window is open and there's no
fixes tag that it isn't).

As an aside, I meant to send the driver once the merge window closes, so
thanks for spotting a problem with the driver before I even sent it :)

Thanks,
Conor.
