There is a standard binding available for this: "non-removable"
There should not be a need to introduce a TI specific binding for this
(I know this is not your fault).

I will send a patch to change the existing .dts files and update the
driver - can you drop this line for now so we don't introduce more
incompatibilities? I can send a patch adding "non-removable" to this
node as part of my clean-up series.

Thanks,
Sekhar
