1NVIDIA Tegra20/Tegra30/Tegr114/Tegra124 fuse block. 2 3Required 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 Otherwise, must contain "nvidia,<chip>-efuse", plus one of the above, where 8 <chip> is tegra132. 9 Details: 10 nvidia,tegra20-efuse: Tegra20 requires using APB DMA to read the fuse data 11 due to a hardware bug. Tegra20 also lacks certain information which is 12 available in later generations such as fab code, lot code, wafer id,.. 13 nvidia,tegra30-efuse, nvidia,tegra114-efuse and nvidia,tegra124-efuse: 14 The differences between these SoCs are the size of the efuse array, 15 the location of the spare (OEM programmable) bits and the location of 16 the speedo data. 17- reg: Should contain 1 entry: the entry gives the physical address and length 18 of the fuse registers. 19- clocks: Must contain an entry for each entry in clock-names. 20 See ../clocks/clock-bindings.txt for details. 21- clock-names: Must include the following entries: 22 - fuse 23- resets: Must contain an entry for each entry in reset-names. 24 See ../reset/reset.txt for details. 25- reset-names: Must include the following entries: 26 - fuse 27 28Example: 29 30 fuse@7000f800 { 31 compatible = "nvidia,tegra20-efuse"; 32 reg = <0x7000F800 0x400>, 33 <0x70000000 0x400>; 34 clocks = <&tegra_car TEGRA20_CLK_FUSE>; 35 clock-names = "fuse"; 36 resets = <&tegra_car 39>; 37 reset-names = "fuse"; 38 }; 39 40 41
