The Video Protection Region (VPR) found on NVIDIA Tegra chips is a region of memory that is protected from CPU accesses. It is used to decode and play back DRM protected content.
It is a standard reserved memory region that can exist in two forms: static VPR where the base address and size are fixed (uses the "reg" property to describe the memory) and a resizable VPR where only the size is known upfront and the OS can allocate it wherever it can be accomodated.
