Subject: [PATCH v5 1/8] of: Add NVIDIA Tegra SATA controller binding

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
