Add a new driver for the TouchNetix's axiom family of touchscreen
controller. This driver only support i2c and can be later adapted for
SPI and USB support.

Above is the missing changelog:
Changes in v2:
- Add device tree binding documentation
- Move core functions in axiom_i2c as we only care about i2c support now
- Use static function when required
- Use syntax dev_err_probe()
- Add an hardware based reset
Changes in v3:
- Remove irq-gpios property in dt-binding
- Use a generic node name
- Fix issues reported in https://lore.kernel.org/oe-kbuild-all/[email protected]/
Changes in v4:
- Cleanup unused headers and macros
- Use standard kernel type
- Namespace structures and functions
- Use packed struct when possible to avoid bitfield operators
- Fix missing break when address is found in axiom_populate_target_address()
- Split reads in two steps for the reports, first length then report
itself so we only read required bytes
- Get poll-interval from devicetree
- Add VDDI/VDDA regulators
- Add a startup delay of 110 ms required after VDDA/VDDI is applied
- Remove axiom_i2c_write() as it is no more used
Changes in v5:
- Fix wrong message constructed in axiom_i2c_read
- Delay required between i2c reads is >= 250us
- Do not split report reading in two phases as we'll
have to wait 500us
- Use lower-case in properties names
- Make regulators properties are required in dt-binding
- Fix bug report: https://lore.kernel.org/lkml/[email protected]/
- Fix bug report: https://lore.kernel.org/lkml/[email protected]/
Changes in v6:
- Fix missing unevaluatedProperties.in dt-binding
- Use __le16 to correctly deal with device endianness
- Use standart kernel types s/char/u8/
- Use regmap api as driver might support spi later
- Use get_unaligned_le16() for the sake of clarity
- Use devm_regulator_enable_optional()
Changes in v7:
- Remove startup time from dt-binding
- Fix usage table not correctly populated
Changes in v8:
- Fix missing call to input_report_slot_state()
- Fix issue reported in https://lore.kernel.org/oe-kbuild-all/[email protected]/
Changes in v9:
- Fix issue reported in https://lore.kernel.org/oe-kbuild-all/[email protected]/
- Rebase on v6.8-rc2

Hello,
Now that all the comments are addressed, do you think there is a chance
that this driver could be merged for 6.9?
Regards,
