[PATCH 0/2] arm64: tegra: Lost patches for v4.10-rc1

[Thierry Reding]

From: Thierry Reding <treding-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

Hi ARM SoC maintainers,

As discussed on IRC, resending these two that seem to have fallen
through the cracks. At least the first patch had been part of a pull
request for v4.8 but ended up not being merged (although all the other
patches in the request did).

Anyway, it'd be great to get these applied for v4.10-rc1.

Thanks,
Thierry

[PATCH 1/2] arm64: tegra: Add VDD_GPU regulator to Jetson TX1

[Thierry Reding]

From: Alexandre Courbot <acourbot-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

Add the VDD_GPU regulator (a GPIO-enabled PWM regulator) to the Jetson
TX1 board. This addition allows the GPU to be used provided the
bootloader properly enabled the GPU node.

[PATCH 2/2] arm64: tegra: Add missing Smaug revision

[Thierry Reding]

From: Alexandre Courbot <acourbot-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

The "google,smaug-rev2" string is missing from the compatible list of
Smaug's DT. The differences of rev2 are not relevant at our current
level of support and it boots just fine, so add it.

Applied both to next/fixes-non-critical for v4.10-rc1, and added
a cc:stable tag for the first one to trigger backports for
4.5+. Thanks,
