So here's v5: this time, as suggested, I handle the sata clock myself
and let ahci_platform handle it too, leading it to be prepared+enabled
twice. This works fine, and allows us to remove the DT ordering requirement.
I also have in the works a patchset that adds the name-based
ahci_platform_get_resources function, but that is not quite ready yet,
even if it is quite far along. Also, I am going on vacation and
returning on 28.7., so if this v5 is acceptable maybe it could be merged
for 3.17 and I could work on the new get_resources scheme after I get
back from vacation?
Thanks, Mikko
