Merge tag 'regulator-v6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
"This is a very quiet release for regulator, almost all the changes are
new drivers but we do also have some improvements for the Rust
bindings.

- Additional APIs added to the Rust bindings

- Support for Maxim MAX77838, NXP PF0900 and PF5300, Richtek RT5133
and SpacemiT P1"

Changes in v3:

binding part
- change regulator node names into lowercase.
- add more description for nxp,i2c-crc-enable.
- remove the unnecessary nxp,dvs-run/standby-voltage property.
These changes come from review comments:
https://lore.kernel.org/imx/e9f38e38-7df7-4d19-b5c0-2f18aeebcc78@kernel.org/
- add regulator-state-mem property for example.

driver part
- convert to use maple tree register cache.
- change of_match_ptr() name to lowercase since dt-binding changed.
- add more nxp,i2c-crc-enable description for commit message.
- remove the of_parse_cb and dvs from pf0900_regulators since the
unnecessary property nxp,dvs-run/standby-voltage removed.
- add set_suspend_enable/disable/voltage for the SW regulator_ops.
the run/standby voltage can be adjusted via the API which regulator
driver provides is recommended.
These changes come from binding review comments:
https://lore.kernel.org/imx/e9f38e38-7df7-4d19-b5c0-2f18aeebcc78@kernel.org/
- add bitfield.h header due to build issue.
- correct the sw4 id.
- add PF0900 prefix for short macro define in order to avoid duplication.
- merge the same mask define in order to simplify code.
- Link to v2: https://lore.kernel.org/r/20250721-b4-pf09-v2-v2-0-e2c568548032@nxp.com

Changes in v2:

binding part
- modify the binding file name to match compatible string.
- add one space for dt_binding_check warning.
- remove unnecessary quotes from "VAON".
- remove the unnecessary empty line.
- move unevaluatedProperties after the $ref.
- move additionalProperties after regulator type.
- remove unnecessary regulator description

driver part
- modify the copyright comment block to C++ style.
- add reg_read/write for regmap_bus.
- remove original pf0900_pmic_read/write.
- remove many regulator operations.
- use regmap_read replace pf0900_pmic_read.
- use regmap_update_bits and regmap_write_bits replace pf0900_pmic_write.
- move the code from pf0900.h to pf0900-regulator.c and delete the header file.
- remove unmask status interrupts and add unmask regulator interrupts.
- remove many interrupts check warning print from irq_handler.
- add notifier for regulator event.
- remove unused macro define.
- add PF0900 prefix for IRQ macro define in order to avoid duplication.
- use GENMASK() and BIT() to replace mask marco define
- remove redundant enum pf0900_chip_type.
- remove redundant print info and comments.
- add dvs property present check because this property is optional.
- remove ret == -EINVAL check from sw_set_dvs() function.

regulator: pf0900: Add PMIC PF0900 support

The PF0900 is a power management integrated circuit (PMIC) optimized
for high performance i.MX9x based applications. It features five high
efficiency buck converters, three linear and one vaon regulators. It
provides low quiescent current in Standby and low power off Modes.
