As of v6 of the series, the original header from the kernel seems to be working as is, so there's no need to split it anymore. However, I'll plan to incorporate your suggestion as a separate series, if it's okay :) I was looking into this though and could only find some utilities such as tools/iio/, tools/spi/, and so on, which seem to create a symbolic link to the header present in the kernel (rather than copying). Is this what you were referring to? Regards, Raghavendra
