Subject[PATCH v2 0/2] Migrate PCIe-IDIO-24 GPIO driver to the regmap API
Date
Changes in v2:
- Simplify PCIe-IDIO-24 register offset defines to remove superfluous
arithmetic
- Check for NULL pointer after chip->irq_drv_data allocation
- Set gpio_regmap drvdata and use gpio_regmap_get_drvdata() to get the
regmap in idio_24_reg_map_xlate()

The regmap API supports IO port accessors so we can take advantage of
regmap abstractions rather than handling access to the device registers
directly in the driver.

A patch to pass the device regmap and irq_drv_data as a parameters for
the struct regmap_irq_chip set_type_config() is included. This is needed
by idio_24_set_type_config() in order to update the type configuration
on the device as well as irq_drv_data for idio_24_handle_mask_sync().

William Breathitt Gray (2):
regmap: Pass regmap and irq_drv_data as parameters for
set_type_config()
gpio: pcie-idio-24: Migrate to the regmap API
