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

From: William Breathitt Gray
Date: Sun Mar 26 2023 - 18:06:16 EST


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.
