The SpacemiT P1 is an I2C-controlled PMIC that implements 6 buck
converters and 12 LDOs.  It contains a load switch, ADC channels,
GPIOs, a real-time clock, and a watchdog timer.

This series introduces a multifunction driver for the P1 PMIC as
well as drivers for its regulators and RTC.

The content of this version is identical to the previous one.
It has simply been rebased onto Linux v6.17-rc1.

Between version 11 and version 12:
  - Simple rebase

Here is version 11 of this series:
  https://lore.kernel.org/lkml/20250803025812.373029-1-elder@riscstar.com/

Between version 10 and version 11:
  - Abandon trying to implement a simple_mfd_data->max_register field
  - Fix a missing dependency pointed out by the kernel test robot

Here is version 10 of this series:
  https://lore.kernel.org/lkml/20250726131003.3137282-1-elder@riscstar.com/

Between version 9 and version 10:
  - The #address-cells and #size-cells for the i2c8 DTS node
    were moved into its primary definition in "k1.dtsi".
  - The interrupts property for the i2c8 DTS node was moved
    below its clock-related properties.
  - The status property in the pmic@41 DTS node was dropped.
  - The function that provides the regmap_config structure
    to use was reworked a bit.
  - A new function was added to free the regmap_config
    structure after it's no longer needed.

Here is version 9 of this series:
  https://lore.kernel.org/lkml/20250724202511.499288-1-elder@riscstar.com/

Between version 8 and version 9:
  - The max_config value is always used if it is provided with the
    simple_mfd_data structure.
  - The regmap_config structure used is allocated dynamically if
    necessary; otherwise regmap_config_8r_8v is used.
  - A small duplicated comment is removed

Here is version 8 of this series:
  https://lore.kernel.org/lkml/20250710175107.1280221-1-elder@riscstar.com/
