1 NVEC: An NVidia compliant Embedded Controller Protocol Implemenation
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.
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.
