My mistake, I forgot to push it out.

I checked the other branches now and found two other commits missing
in next/fixes-non-critical:


arm64: tegra: Add missing Smaug revision
arm64: tegra: Add VDD_GPU regulator to Jetson TX1

Both sent by Thierry Reding last Friday. I can add them back on top
or you pick them up again if you are already busy doing merges.

For the first patch, I had amended the changelog text, this is the
version I had.

Subject: [PATCH] arm64: tegra: Add VDD_GPU regulator to Jetson TX1

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.

[as pointed out by Thierry on IRC, nobody has reported a bug
 in the field, but using a new bootloader with a .dtb that
 has the incorrect data, it will crash on boot]
