1 | What: /sys/devices/*/<our-device>/fuse | ||
2 | Date: February 2014 | ||
3 | Contact: Peter De Schrijver <pdeschrijver@nvidia.com> | ||
4 | Description: read-only access to the efuses on Tegra20, Tegra30, Tegra114 | ||
5 | and Tegra124 SoC's from NVIDIA. The efuses contain write once | ||
6 | data programmed at the factory. The data is layed out in 32bit | ||
7 | words in LSB first format. Each bit represents a single value | ||
8 | as decoded from the fuse registers. Bits order/assignment | ||
9 | exactly matches the HW registers, including any unused bits. | ||
10 | Users: any user space application which wants to read the efuses on | ||
11 | Tegra SoC's | ||
