Subject: [PATCH v4 0/4] Migrate IDIO-16 GPIO drivers to regmap API
Date:   Fri, 31 Mar 2023 17:05:22 -0400

Changes in v4:
 - Remove superfluous base check in idio_16_reg_mask_xlate()
 - Format idio_16_names[] to 8 GPIO per line
 - Utilize dev_err_probe() in idio_16_regmap_register()

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.

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.

This patchset depends on the "Drop map from handle_mask_sync()
parameters" patchset [0].
