- include previously removed patch:
  'dt-bindings: power: supply: max17042: add max77705 support'
- use same of_node for matching simple-mfd-i2c and setting max17042
  driver
- Link to v12: https://lore.kernel.org/r/20241217-starqltechn_integration_upstream-v12-0-ed840944f948@gmail.com

Changes in v12:
