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.
