Patches 7 and 8 were for soc/tegra and dt-bindings, respectively. Patches 9-11 were for the PHY subsystem, so you may have missed them because they were not contiguous within the series. The reason is that patch 9 depends on patch 7, though in retrospect it might have been clearer to put 7 and 8 before the whole set of the PHY patches. Apologies for that. Could you take a look at 9 through 11? 9 and 11 are pretty big, but it's really just the Tegra210 and Tegra186 specific implementations of the functionality introduced in this patch. I've also fixed up the modular build error that Nathan had pointed out on patch 9. Let me know if you want me to resend that. Thierry
