Changes in v5:
- Split the patch series to refactor LTC2309 channel enums first.
- Explicitly assign hex values to channel enums based on datasheet.
- Add support for LTC2305 on top of the refactored driver.
- Link to v4: https://lore.kernel.org/r/20260311-add_ltc2305_driver-v4-...
Changes in v4:
- Fix build warning in ltc2309_probe(): initialize 'chip_info'.
- Link to v3: https://lore.kernel.org/r/20260126-add_ltc2305_driver-v3-...
Changes in v3:
- Modify ltc2305 channel mask to compatible ltc2309.
- Link to v2: https://lore.kernel.org/r/20251224-add_ltc2305_driver-v2-...
Changes in v2:
- Reordered chip descriptions and code from low to high order.
- Renamed chip info structure to use ltc2309 driver prefix.
- Switched to i2c_get_match_data().
- Removed unused variables.
- Added chip info to i2c_device_id table.
- Link to v1: https://lore.kernel.org/r/20251223-add_ltc2305_driver-v1-...
