I have been creating Rust bindings for bcm2835 lib.
Its incomplete and needs work.
Since I am new to the world of open source, question is how do I select an open source license for the bindings.

Abhijith,
If you have not searched already there are a few sites that
cover the various Open Source Licences and the key elements of
each Open Source License. I would suggest you review those and
simialar Open Source Licence resources to have a feel of the
choices and choose one that suits you.
As a foot note there are those that do not like GPL V3, but
fine with GPL V2 even years after GPL V3 was created. That
means many that were GPL V2 before GPL V3 was created do not
want to change to GPL V3. MIT Type license is another many
use. I am not trying to bias your decision at all. I am no
expert. I do know I have and still read about GPL V2 vs V3 to
this day by chance without seeking to do so.
I do not know if there is a place/mailing list that focus is
about Open Source Licenses, but maybe you might find ther eis
and if so likely good place to ask and discuss choices that
suit you.
