In a subsequent patch 7/9 we remove direct gpio_chip registration in favor of the i8255 library registration via gpio_regmap. It doesn't look like gpio_regmap_register() sets the init_hw() callback. Michael, do you see any issues if I introduce init_hw() to gpio_regmap_config? Or do you think this IRQ initialization belongs somewhere else? William Breathitt Gray
