Hello,
I am looking to design an upstreamable driver for a custom SAS host controller and I have a question on libsas: the documentation for libsas states that the LLDD is a pci device driver - is this necessary? Our HBA is connected on the system bus, so would require a platform driver.
Regards,
John

A quick look through the sources would tell you the answer to this:
"no" (except there's one printk which might need fixing in
sas_discover.c). I think the docs date back to before the pcidev->dev
conversion was done.
