-NVIDIA Tegra20/Tegra30/Tegr114/Tegra124 fuse block.
-
-Required properties:
-- compatible : For Tegra20, must contain "nvidia,tegra20-efuse".  For Tegra30,
-  must contain "nvidia,tegra30-efuse".  For Tegra114, must contain
-  "nvidia,tegra114-efuse".  For Tegra124, must contain "nvidia,tegra124-efuse".
-  For Tegra132 must contain "nvidia,tegra132-efuse", "nvidia,tegra124-efuse".
-  For Tegra210 must contain "nvidia,tegra210-efuse". For Tegra186 must contain
-  "nvidia,tegra186-efuse". For Tegra194 must contain "nvidia,tegra194-efuse".
-  For Tegra234 must contain "nvidia,tegra234-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";
-	};
