Hey Abhilash, Aswin, Balaji, Varda,
Just wanted to reiterate the general OF_UPSTREAM DT guideline below.

Why aren't you upstreaming these?

Please don't push any DT overrides in U-Boot without any upstream path
to get rid of DT overrides in future. Always provide a link to upstream
kernel DT posting whenever any exception is needed to add DT overrides
in U-Boot. This applies to all the patch-sets adding DT overrides
especially in case of U-Boot SPL support series.
bootph-all is well upstream kernel DT accepted approach, so first go for
kernel DT updates always.
