    Subject[PATCH 0/6] Migrate IDIO-16 GPIO drivers to regmap API
    Date
    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. The 104-idio-16 and pci-idio-16 modules depend
    on the IDIO-16 library and are thus updated accordingly.

    The 104-IDIO-16 lacks a status register (as does the 104-DIO-48E), so a
    no_status flag is introduced to the regmap-irq API to properly handle
    such cases and avoid hacks. The 104-dio-48e module is updated in a
    subsequent patch to take advantage of this new no_status flag.

    By leveraging the regmap API, the idio-16 library is reduced to simply a
    devm_idio_16_regmap_register() function and a configuration structure
    struct idio_16_regmap_config.

    William Breathitt Gray (6):
    regmap-irq: Add no_status support
    gpio: 104-dio-48e: Utilize no_status regmap-irq flag
    gpio: idio-16: Migrate to the regmap API
    gpio: 104-idio-16: Migrate to the regmap API
    gpio: pci-idio-16: Migrate to the regmap API
    gpio: idio-16: Remove unused legacy interface
