this reverts commit ce58459d8c7f4174e7b8a8ea903dd949631334a3 for imx8mq.
this is most likely not the real fix but works around the problem I have (with v5.12-rc2) I want to report:
[ 0.766925] SoC revision 0x21 [ 0.770286] imx8_soc_info soc@0: SoC revision via nvmem read failed: -517
This leads to the system not booting up.
This change makes use of the old way of reading soc_revision and thus works around the problem.
What could be missing for the nvmem way to work here? Should it work in any case? I assume so if you add the compatible to imx8mq.dtsi. But if it would work, why keep the ocotp reads?
thanks a lot, martin
