The keyboard is > not attached to the EC's PS/2 port. It is on a matrix of GPIOs. And still you are using only one GPIO in your driver? While WPCE775x does seem to have matrix keypad support I think that you are using one of the 3 PS/2 ports, like your touchpad does. > > I was trying to explain that even though the firmware on the EC uses > 0xF4 written over i2c to initialize it, it doesn't appear to support > other PS/2 commands directed to the keyboard on the GPIO matrix. > The device is initialized with 0xf4; the device is supposed to respond with 0xfa; I wonder what scancodes the device reports... It smells strongly of PS/2. Also, it is not controller that supports PS/2 commands but rather the device itself so I am still hopeful that we could make use of the standard drivers. Wan, you worked at Nuvoton, do you know if wpce775 fully supports PS/2 interface? -- Dmitry -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
