- * This driver uses the Chrome OS EC byte-level message-based protocol for
- * communicating the keyboard state (which keys are pressed) from a keyboard EC
- * to the AP over some bus (such as i2c, lpc, spi). The EC does debouncing,
- * but everything else (including deghosting) is done here. The main
- * motivation for this is to keep the EC firmware as simple as possible, since
- * it cannot be easily upgraded and EC flash/IRAM space is relatively
- * expensive.
