[PATCH 1/2] dt-bindings: fuse: Document compatible string for Tegra264 FUSE

[PATCH 1/2] dt-bindings: fuse: Document compatible string for Tegra264 FUSE

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

This hardware block is mostly the same as the one found on earlier
generations. However, the exact register regions that can be accessed
differ, so a new compatible string is required.

[PATCH 2/2] arm64: tegra: Add FUSE block on Tegra264

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

The FUSE block contains a number of registers exposing information that
is useful for certain drivers and/or userspace to read at runtime.

New compatible string is always needed.

Confusing commit msg, same comments as for other patchset.
