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