Thank you for the suggestion. I am not familiar with GPIO_REGMAP and REGMAP_IRQ so I will read about it. Is the advantage is that is helps to reduce code duplication by using an abstraction?
I did notice that the gpio-sifive.c driver used regmap_update_bits() and regmap_write().
I suppose that is better than writel_relaxed() and iowrite32() which this RFC driver does?
thanks, drew
