I was told that the main purpose for the chips in question (specifically 3-axis accelerometers) is to be used as HIDs.

No, I do not believe that maintaining 2 separate devices for the same hardware with the only difference is how data is presented to userspace is a viable option. > > My hope is that we can make use of a well known and uniform > API for all input devices in a device, be it a keypad, > touchscreen, accelerometer, magnetometer, gyro, or whatever. > If only we could agree what input devices are... -- Dmitry -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
