Alexandre Courbot 5e6b9a89af 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]

Thierry Reding 7793426943 arm64: tegra: Add PMIC support on Jetson TX1
Add a device tree node for the MAX77620 PMIC found on the p2180
processor module (Jetson TX1). Also add supporting power supplies,
such as the main 5 V system supply.

Thierry Reding be70771d4c arm64: tegra: Remove 0, prefix from unit-addresses
When Tegra124 support was first merged the unit-addresses of all devices
were listed with a "0," prefix to encode the reg property's second cell.
It turns out that this notation is not correct, and the "," separator is
only used to separate fields in the unit address (such as the device and
function number in PCI devices), not individual cells for addresses with
more than one cell.

Thierry Reding 9e71045f1b arm64: tegra: Add NVIDIA Jetson TX1 support
The NVIDIA Jetson TX1 is a processor module that features a Tegra210 SoC
with 4 GiB of LPDDR4 RAM attached, a 32 GiB eMMC and other essentials.

It is typically connected to some I/O board (such as the P2597) that has
the connectors needed to hook it up to the outside world.
