+What: /sys/devices/*/<our-device>/fuse
+Date: February 2014
+Contact: Peter De Schrijver <pdeschrijver@nvidia.com>
+Description: read-only access to the efuses on Tegra20, Tegra30, Tegra114
+ and Tegra124 SoC's from NVIDIA. The efuses contain write once
+ data programmed at the factory. The data is layed out in 32bit
+ words in LSB first format. Each bit represents a single value
+ as decoded from the fuse registers. Bits order/assignment
+ exactly matches the HW registers, including any unused bits.
+Users: any user space application which wants to read the efuses on
+ Tegra SoC's

- It was decided to remove plat-s5pc1xx as some of the support was already

+NVIDIA Tegra20/Tegra30/Tegr114/Tegra124 fuse block.
+
+Required properties:
+- compatible : should be:
+ "nvidia,tegra20-efuse"
+ "nvidia,tegra30-efuse"
+ "nvidia,tegra114-efuse"
+ "nvidia,tegra124-efuse"
+ Details:
+ nvidia,tegra20-efuse: Tegra20 requires using APB DMA to read the fuse data
+ due to a hardware bug. Tegra20 also lacks certain information which is
+ available in later generations such as fab code, lot code, wafer id,..
+ nvidia,tegra30-efuse, nvidia,tegra114-efuse and nvidia,tegra124-efuse:
+ The differences between these SoCs are the size of the efuse array,
+ the location of the spare (OEM programmable) bits and the location of
+ the speedo data.
+- reg: Should contain 1 entry: the entry gives the physical address and length
+ of the fuse registers.
+- clocks: Must contain an entry for each entry in clock-names.
+ See ../clocks/clock-bindings.txt for details.
+- clock-names: Must include the following entries:
+ - fuse
+- resets: Must contain an entry for each entry in reset-names.
+ See ../reset/reset.txt for details.
+- reset-names: Must include the following entries:
+ - fuse
+
+Example:
+
+ fuse@7000f800 {
+ compatible = "nvidia,tegra20-efuse";
+ reg = <0x7000F800 0x400>,
+ <0x70000000 0x400>;
+ clocks = <&tegra_car TEGRA20_CLK_FUSE>;
+ clock-names = "fuse";
+ resets = <&tegra_car 39>;
+ reset-names = "fuse";
