The i.MX6UL has a SPDIF located at start address 0x02004000 in the
AIPS-1 memory region [1].
SPDIF is also available on i.MX6ULL [2], so imx6ull.dtsi is fine.

03/2017, Table-2-2 AIPS-1 memory map, p. 158
[2] i.MX 6ULL Applications Processor Reference Manual, Rev. 1,
11/2017, Table-2-2 AIPS-1 memory map, p. 178

The patch looks good.
Did you have a chance to test this on your hardware?
Thanks

Hi Fabio,
yes, I am running it on a custom i.MX6ULL board:
```
imx-spdif sound-spdif: snd-soc-dummy-dai <-> 2004000.spdif mapping ok
```
Best regards
Jörg Krause

New compatible needs to be documented.
