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. + +[1] e.g. http://nv-tegra.nvidia.com/gitweb/?p=linux-2.6.git;a=tree;f=arch/arm/mach-tegra/nvec;hb=android-tegra-2.6.32 +[2] http://gitorious.org/ac100, http://launchpad.net/ac100 -- cgit v1.3.1
