[PATCH v5 1/8] of: Add NVIDIA Tegra SATA controller binding
From: mperttunen@nvidia.com (Mikko Perttunen)
Date: 2014-07-18 07:16:21
Also in:
linux-ide, linux-tegra, lkml
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?
