I might be able to update the gpio-i8255 functions to take advantage of
gpio-regmap, but the changes in the precursor patches are primarily to
handle the device interrupts. Currently, I call gpio_irq_chip_set_chip()
to assign the struct irq_chip structure to the struct gpio_irq_chip
structure. What would be the equivalent for gpio-regmap?
