[v4,00/20] mfd: adp5585: support keymap events and drop legacy Input driver

Hi all,

Here it goes v4. Main changes is to drop chip info based struct and
directly use an enum in the FW .data pointer, use the notifier API for
dispatching events and multiple calls to mfd_add_devices().

Regarding the last point, I think I could have used multiple calls to
devm_mfd_add_devices() and avoid those gotos in adp5585_add_devices()
but I do not feel that would have been "correct".

Thanks!

Changes in v4:
 - Patch 2:
   * Directly use mfd_add_devices() to individually add devices

 - Patch 3:
   * Don't break lines at 80;
   * Add comment suggested by Laurent;
   * PWM change squashed in this patch.

 - Patch 5:
   * Pass an enum to the of_id data pointer;
   * Reference the regmap defaults directly from the variant enum;
   * Drop chip_info struct and place data directly in struct adp5585_dev.

 - Patch 6:
   * Adapt to the new way of passing per variant data;
   * Rename adp5585_fill_regmap_config() to adp5585_fill_variant_config();
   * Add struct device now to struct adp5585_dev;
   * Pass adp5585_dev to adp5585_add_devices().

 - Patch 7:
   * Add regs directly in struct adp5585_dev.

 - Patch 9:
   * Moved the per variant gpio register into the gpio driver;
   * Moved ADP558[59]_GPIO_{BANK_BIT} into the gpio driver;
   * Moved ADP5589_GPIO_MAX and dropped the max_{col|row}.

 - Patch 10:
   * Adapt to the lack of a chip_info pointer when getting ext_cfg.

 - Patch 12:
   * Refactor parsing of poll-interval;
   * Make use of the notifier API instead of "own" dispatcher mechanism;
   * Improve comments in the code.

 - Patch 13:
   * Add more comments;
   * Drop the function callback for validating events;
   * Renamed has_pin5 to has_pin6;
 
 - Patch 14:
   * Adapt to the new way of adding MFD cells;
   * Improve comments.

 - Patch 15:
   * Use the notifier API and adapt to that.

 - Patch 16:
   * Use the notifier API and adapt to that;
   * Move devm_add_action_or_reset() before the for() loop setting the
     bits in kpad->keypad;
   * Address Dmitry comment about checking for error instead of
     directly returning when calling adp5585_keys_check_special_events().
