0001 NVEC: An NVidia compliant Embedded Controller Protocol Implementation
0002
0003 This is an implementation of the NVEC protocol used to communicate with an
0004 embedded controller (EC) via I2C bus. The EC is an I2C master while the host
0005 processor is the I2C slave. Requests from the host processor to the EC are
0006 started by triggering a gpio line.
0007
0008 There is no written documentation of the protocol available to the public,
0009 but the source code[1] of the published nvec reference drivers can be a guide.
0010 This driver is currently only used by the AC100 project[2], but it is likely,
0011 that other Tegra boards (not yet mainlined, if ever) also use it.
