Given that the only comments were bikeshed from my part, do you have any objections to me taking the patch and apply the bikeshed myself? > "clocksource: tegra: wrap arch/arm-specific sections in CONFIG_ARM" > https://git.kernel.org/cgit/linux/kernel/git/pjw/tegra-dev.git/commit/?id=220aa7fcc74a1a089916be6cb34b0e326f31841f I don't think I've seen any comments other than mine on this patch. Given that this patch depends on the above to get rid of the BROKEN dependency, it might still be preferable to take both via the Tegra tree. Otherwise we probably have to wait until v3.21 before we can apply this. Thierry

I got distracted with some other patches and haven't yet reposted that one :-( I will do that later today. If you would prefer to do it yourself, that's fine too. >> "clocksource: tegra: wrap arch/arm-specific sections in CONFIG_ARM" >> https://git.kernel.org/cgit/linux/kernel/git/pjw/tegra-dev.git/commit/?id=220aa7fcc74a1a089916be6cb34b0e326f31841f > I don't think I've seen any comments other than mine on this patch. > Given that this patch depends on the above to get rid of the BROKEN > dependency, it might still be preferable to take both via the Tegra > tree.

Generally my preference is for patches to go in through the direct maintainer's tree to minimize the risk and hassle of merge conflicts. But if you'll take care of that side of it, it doesn't matter too much to me :-) We just need to pick up acks from the direct maintainers, I guess? - Paul -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I ended up applying your patch as is. Retrospectively my comments had been a little too much on the pedantic side. > >>"clocksource: tegra: wrap arch/arm-specific sections in CONFIG_ARM" > >>https://git.kernel.org/cgit/linux/kernel/git/pjw/tegra-dev.git/commit/?id=220aa7fcc74a1a089916be6cb34b0e326f31841f > >I don't think I've seen any comments other than mine on this patch. > >Given that this patch depends on the above to get rid of the BROKEN > >dependency, it might still be preferable to take both via the Tegra > >tree.

Yes, we really just need an ack from either Daniel or Thomas on the clocksource patch. I don't think that driver has a lot of potential for merge conflicts. Thierry

Add basic Kbuild support for the Tegra SoC family, and specifically, the Tegra132 SoC. Tegra132 pairs the NVIDIA Denver CPU complex with the SoC integration of Tegra124 - hence the use of ARCH_TEGRA and the Tegra124 pinctrl option. For the time being, Tegra ARM64 support is added with a dependency on CONFIG_BROKEN.
