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";
