Merge tag 'mfd-next-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd

Pull MFD updates from Lee Jones:
 "New Device Support:
   - Add support for X-Powers AXP717 PMIC to AXP22X
   - Add support for Rockchip RK816 PMIC to RK8XX
   - Add support for TI TPS65224 PMIC to TPS6594

  New Functionality:
   - Add Power Off functionality to Rohm BD71828
   - Allow I2C SMBus access in Renesas RSMU

  Fix-ups:
   - Device Tree binding adaptions/conversions/creation
   - Shift Intel support over to MSI interrupts
   - Generify adding platform data away from being ACPI specific
   - Use device core supplied attribute to register sysfs entries
   - Replace hand-rolled functionality with generic APIs
   - Utilise centrally provided helpers and macros
   - Clean-up error handling
   - Remove superfluous/duplicated/unused sections
   - Trivial; spelling, whitespace, coding-style adaptions
   - More Maple Tree conversions"
