Hello,

you're missing:

- dt-bindings (make dtbs_check is unhappy)
- a commit message
- Co-developed-by for Sricharan


status should read "okay" instead, but in this case it's unnecessary
as you're defining the node and lack of the status property also means
that device is enabled

however

this ECC engine seems to be a part of the NAND controller, so it's
unlikely that the DT maintainers will agree for it to have a separate
node
