I will remove the ST code and polling completely.
However, I would like to keep the MT Protocol A. Our solution allows
The platform builder to select to use MT protocol B or not as part of
platform_data in the board configuration. If it makes more sense,
I can reverse the code to default to protocol B and allow the platform
builder developer to select protocol A.
Thank you for the invitation to submit to the mtdev project.
I defer to Dmitry if I should make the next update into the mtdev
project.
Thank you for your review.
