[PATCH 0/3] gpio-regmap support for register fields and other hooks

Posted by Aidan MacDonald 3 years, 9 months ago

This is a small series to expand the usefulness of gpio-regmap.

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.

Aidan MacDonald (3):
  gpio: regmap: Support registers with more than one bit per GPIO
  gpio: regmap: Support combined GPIO and pin control drivers
  gpio: regmap: Support a custom ->to_irq() hook
