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/202310100300.oAC2M62R-lkp@xxxxxxxxx/

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/202312051457.y3N1q3sZ-lkp@xxxxxxxxx/
 - Fix bug report: https://lore.kernel.org/lkml/6f8e3b64-5b21-4a50-8680-063ef7a93bdb@suswa.mountain/

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/202402020623.8T1Ah513-lkp@xxxxxxxxx/

Changes in v9:
 - Fix issue reported in https://lore.kernel.org/oe-kbuild-all/202402201157.BKo97uWl-lkp@xxxxxxxxx/
 - Rebase on v6.8-rc2
