Subject: [PATCH v3 0/2] Migrate STX104 to the regmap API

Changes in v3:
 - Add STX104_ prefixes to defines to avoid potential name classes
 - Rename SAME_CHANNEL() to STX104_SINGLE_CHANNEL() to convey intention
   better
 - Utilize u8_encode_bits() to define STX104_SOFTWARE_TRIGGER
 - Adjust to utilize reg_base members in regmap_config structures
 - Fix off-by-one errors in aio_data_wr_ranges[], aio_data_rd_ranges[],
   and aio_data_regmap_config max_register
 - Inline gpio_config initialization to avoid zeroing it at declaration
 - Add blank lines between register map init blocks for clarity
 - Utilize regmap_read_poll_timeout() for ADC conversion status poll
Changes in v2:
 - Relocate struct stx104_iio for the sake of a clearer patch diff
 - Replace FIELD_PREP() and FIELD_GET() with u8_encode_bits() and
   u8_get_bits()

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 utilize regmap_read_poll_timeout() for polling the ADC
conversion status is included as follow-up to make the git history
clearer for this change.

  iio: addac: stx104: Use regmap_read_poll_timeout() for conversion poll
