    1 NVIDIA Tegra20/Tegra30/Tegr114/Tegra124 fuse block.
    2 
    3 Required properties:
    4 - compatible : For Tegra20, must contain "nvidia,tegra20-efuse".  For Tegra30,
    5   must contain "nvidia,tegra30-efuse".  For Tegra114, must contain
    6   "nvidia,tegra114-efuse".  For Tegra124, must contain "nvidia,tegra124-efuse".
    7   For Tegra132 must contain "nvidia,tegra132-efuse", "nvidia,tegra124-efuse".
    8   For Tegra210 must contain "nvidia,tegra210-efuse". For Tegra186 must contain
    9   "nvidia,tegra186-efuse". For Tegra194 must contain "nvidia,tegra194-efuse".
   10   For Tegra234 must contain "nvidia,tegra234-efuse".
   11   Details:
   12   nvidia,tegra20-efuse: Tegra20 requires using APB DMA to read the fuse data
   13         due to a hardware bug. Tegra20 also lacks certain information which is
   14         available in later generations such as fab code, lot code, wafer id,..
   15   nvidia,tegra30-efuse, nvidia,tegra114-efuse and nvidia,tegra124-efuse:
   16         The differences between these SoCs are the size of the efuse array,
   17         the location of the spare (OEM programmable) bits and the location of
   18         the speedo data.
   19 - reg: Should contain 1 entry: the entry gives the physical address and length
   20        of the fuse registers.
   21 - clocks: Must contain an entry for each entry in clock-names.
   22   See ../clocks/clock-bindings.txt for details.
   23 - clock-names: Must include the following entries:
   24   - fuse
   25 - resets: Must contain an entry for each entry in reset-names.
   26   See ../reset/reset.txt for details.
   27 - reset-names: Must include the following entries:
   28  - fuse
   29 
   30 Example:
   31 
   32         fuse@7000f800 {
   33                 compatible = "nvidia,tegra20-efuse";
   34                 reg = <0x7000f800 0x400>,
   35                       <0x70000000 0x400>;
   36                 clocks = <&tegra_car TEGRA20_CLK_FUSE>;
   37                 clock-names = "fuse";
   38                 resets = <&tegra_car 39>;
   39                 reset-names = "fuse";
   40         };
