Subject: [PATCH v3 0/2] NVIDIA Tegra20 video decoder driver

This driver provides accelerated video decoding to NVIDIA Tegra20 SoC's,
it is a result of reverse-engineering efforts. Driver has been tested on
Toshiba AC100 and Acer A500, it should work on any Tegra20 device.

In userspace this driver is utilized by libvdpau-tegra [0] that implements
VDPAU interface, so any video player that supports VDPAU can provide
accelerated video decoding on Tegra20 on Linux.
