Leo Li (Li Yang) is no longer with NXP. Until we figure out within NXP
how to continue with the maintainership of drivers/soc/fsl/, yes, please
continue to submit this series to 'net'. I would also like to point
out to Arnd that this is the case.
Arnd, a large portion of drivers/soc/fsl/ is networking-related
(dpio, qbman). Would it make sense to transfer the maintainership
of these under the respective networking drivers, to simplify the
procedures?
Also, your patches are whitespace-damaged. They do not apply to the
kernel, and patchwork shows this as well.

Please repost with this fixed.
