Add max22190 gpio driver with input functionality, since device support only input without output. Implemented diagnostic functionality for all 8 channels which include various check to over/under voltage and wire break. Filtering configuration is done from devicetree on per channel bases and is configured on chip start. In case some fault condition occure FAULT pin drive LOW which prop to FAULT registers to be read. Data is stored in data structure for furter analizes and ERR message is printed in console. Signed-off-by: Stoyan Bogdanov <sbogdanov@baylibre.com>
