Hi Tony,
While I understand that you are trying to match the DT data with the
existing legacy data, do you know if there was a reason why this was
omitted in the first place? Should we be really adding the MSTANDBY_
flags and fix up the DTS node accordingly? I tried looking through the
git log, and the initial commit itself didn't add the MSTANDBY_ flags
but used the SYSC_HAS_MIDLEMODE.

Jyri,
Do you know the history?

Suman
