iio: Implement counter channel type and info constants
Quadrature encoders, such as rotary encoders and linear encoders, are devices which are capable of encoding the relative position and direction of motion of a shaft. This patch introduces several IIO constants for supporting quadrature encoder counter devices. IIO_COUNT: Current count (main data provided by the counter device) IIO_INDEX: Counter device index value Signed-off-by: William Breathitt Gray <vilhelm.gray@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
