This driver allows userspace to read the raw efuse data. Its userspace
interface is modelled after the sunxi_sid driver which provides similar
functionality for some Allwinner SoCs. It has been tested on
Tegra20 (ventana), Tegra30 (beaverboard) and Tegra114 (dalmore).

Changes since v1:

* Add documentation for sysfs interface
* Cleanup messages

TODO:
* test on Tegra124 (venice2) 

Peter De Schrijver (6):
  ARM: tegra: export apb dma readl/writel
  misc: fuse: Add efuse driver for Tegra
  ARM: tegra: Add efuse bindings
  ARM: tegra: rework fuse.c
  ARM: Tegra: remove speedo files
  misc: enable fuse drivers
