d8340ed0 | 1 | NVEC: An NVidia compliant Embedded Controller Protocol Implementation |
32890b98 MD |
2 | |
3 | This is an implementation of the NVEC protocol used to communicate with an | |
4 | embedded controller (EC) via I2C bus. The EC is an I2C master while the host | |
5 | processor is the I2C slave. Requests from the host processor to the EC are | |
6 | started by triggering a gpio line. | |
7 | ||
8 | There is no written documentation of the protocol available to the public, | |
9 | but the source code[1] of the published nvec reference drivers can be a guide. | |
10 | This driver is currently only used by the AC100 project[2], but it is likely, | |
11 | that other Tegra boards (not yet mainlined, if ever) also use it. | |
