-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";
- };
