Hi Chris,
Update the Anbernic RGxx3 "device" to use upstream device-trees, add logic to detect a different vdd_cpu regulator, and implement a fix to allow the panel auto-detection to run when using mainline A-TF.
Note that *Linux* still cannot use mainline A-TF because of the missing SCMI clock and reset functionality, but this patch series at least ensures that this board can boot once Linux is ready.
Have you got a link to this upstream in the kernel lists? Is there patches posted? I think I have seen a similar issue when playing with mainline TF-A the other day on the Quartz64.

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.
