Thanks for the ping.

Is there something you need me to do or look at?

For Intel-Atom architectures, the MIPI PTI module does sit on the PCI 
bus.  It's very much dependent upon the PCI bus for working 
functionality and it's not optional.  So yes, it makes sense for the 
driver to depend on PCI to be there and if PCI is not enabled on the 
system, don't build the pti driver.

Maybe it's a Kconfig dependency?

Thanks,
Jay
