I suggest you working with upstream first instead of claiming that
upstream contributions should align with your downstream work. To be
clear: your downstream NXP BSP does not matter.

If you think this submission needs any particular changes, then please
comment on specifics, but such broad statement that community should
wait till NXP will be so kind to allow upstream work is just not acceptable.

Best regards,
