I don't. I just remember when I was testing A-TF previously (I've been following the RK3568 A-TF status since it was first submitted) that it would fail because of missing cpu clocking. Basically the cpu device tree node has a defined link to the SCMI clock that's provided by A-TF. Except that mainline A-TF doesn't do this, so it would get stuck in deferred probe hell. The *real* solution I think is to get SCMI clk and reset support in mainline A-TF, but unfortunately I don't know how to do that at the moment.
