I just realized this is going to cause merge issues across geni serial and geni spi
driver (PATCH 02/17 in this series) unless all of this goes via your tree.
I see this is also an issue with the ongoing ICC patch series [1]

Do you or Greg have any thoughts on how this common header across various drivers
issue should be resolved to avoid conflicts while merging?
