Hello everyone,

this series adds initial support for the NVIDIA Tegra194 "Xavier"
system-on-chip. Initially UART, I2C, SDMMC, as well as the PMIC
are supported, allowing booting to a console.

The changes consist almost completely of the new device trees,
however some fixes are required in the BPMP driver to support the
new channel layout in Tegra194.

The series has been tested on Tegra186 (Jetson TX2) and Tegra194
(P2972).

Cheers,
Mikko
