Messages in this thread | | | From | William Breathitt Gray <> | 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].
