Please use the right comment formats /* text */
Also, just /* eMMC */ would be fine here.

Can we club the following 3 together:
non-removable;
no-sd;
no-sd;

And normally these is a part of board file (.dts), right?

You added interconnects, but not any opp-peak-kBps / opp-avg-kBps,
presumably mistakengly?

Also, 384Mhz + min_svs sounds a bit weird? Is that the correct

Komal,

since you're already touching this file, would you mind making a
separate commit moving status last for all nodes?
