From: Alexandre Courbot <acourbot@xxxxxxxxxx> 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. Signed-off-by: Alexandre Courbot <acourbot@xxxxxxxxxx> Signed-off-by: Thierry Reding <treding@xxxxxxxxxx> --- Hi ARM-SoC maintainers, This was part of a pull request for v4.8 but it seems everything of the pull request except this one patch made it upstream. I think perhaps it may have been the dependency on the regulator tree that made you defer this to after v4.8-rc1 and then I forgot to resend. Here's a link to the pull request: http://lists.infradead.org/pipermail/linux-arm-kernel/2016-July/443469.html There was no discussion on the list, but we might have discussed it on IRC. Can you please pick this up for v4.10-rc1?
