Patch 1 allows GPIO direction and level to be mapped to values in a register field for cases where a one-bit-per-GPIO mapping is insufficient. Patch 2 allows gpio-regmap to be used for the GPIO portion of a combined pin control + GPIO driver by deferring some ops to the pin control subsystem. Patch 3 allows drivers to provide a custom ->to_irq() hook for the GPIO chip as an alternative to using an IRQ domain.
