Please define this in the SoC DTSI and enable it via a &uart1 {} reference
from the board DT

should dma-ranges also be 36-bit?

I see there's only a single QUP wrapper - therefore I'm going to assume
there will never be a SoC where this needs to be disabled

Please uniformly keep a \n before status, file-wide

For OP-TEE, we have use cases like getting the random numbers, 
remoteproc PAS and few others.

For SCM, setting the download mode is one typical example where OP-TEE 
doesn't come into picture.

Please let me know if this helps.

I think it does, but it's odd that OPTEE wouldn't handle both

fwiw +Sumit is poking at OSS firmware for other platforms and may be
interested

The SCM calls are the ones handled by TF-A which are usually referred
to as SiP SMC calls. OP-TEE doesn't handle those SiP calls but only
the SMC calls in trusted OS range. So yeah both nodes have to be
there.

I think this is a WIN family chipset which only supports OP-TEE by
default. In the IoT chipsets there can either be QTEE or OP-TEE and
the bootloader (U-Boot) apply a DT fixup for OP-TEE in case it's
present.
