| If you say Y here, you get support for talking to the ChromeOS EC |
| over an LPC bus. This uses a simple byte-level protocol with a |
| checksum. This is used for userspace access only. The kernel |
| typically has its own communication methods. |
| |
| To compile this driver as a module, choose M here: the |
| module will be called cros_ec_lpc. |
