NXP 74HC153 is a GPIO expander. Its original source cide sits in ar71xx architecture tree. It has been slightly modified to get GPIO pin configuration from the device tree rather than a MACH file. Changes to the source file: - Remove struct nxp_74hc153_config - in nxp_74hc153_probe(), fetch GPIO configuration from device tree - allow GPIO framework decide the base number by passing -1 to it - remove support for kernel versions below 4.5.0 - add OF device compatibility string Create a package for inclusion in image.
