v4:
- Add missing maxitems dt-bindings property

v3:
- Merge dt-bindings into i2c-mux-pca954x.yaml

v2:
- Move dt-bindings to separate file
- Added support for MAX736x as they are very similar
- Fixed an issue found by kernel test robot
- Dropped max735x property and custom IRQ check
- Added MAX7357 config register defines instead of magic values
- Renamed vcc-supply to vdd-supply

Patrick Rudolph (3):
  dt-bindings: i2c: Add Maxim MAX735x/MAX736x variants
  i2c: muxes: pca954x: Add MAX735x/MAX736x support
