Merge tag 'mfd-next-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd

Pull MFD updates from Lee Jones:
"Samsung Exynos ACPM:
- Populate child platform devices from device tree data
- Introduce a new API, 'devm_acpm_get_by_node()', for child devices
to get the ACPM handle

ROHM PMICs:
- Add support for the ROHM BD96802 scalable companion PMIC to the
BD96801 core driver
- Add support for controlling the BD96802 using the BD96801 regulator
driver
- Add support to the BD96805, which is almost identical to the
BD96801
- Add support to the BD96806, which is similar to the BD96802

Maxim MAX77759:
- Add a core driver for the MAX77759 companion PMIC
- Add a GPIO driver for the expander functions on the MAX77759
- Add an NVMEM driver to expose the non-volatile memory on the
MAX77759

STMicroelectronics STM32MP25:
- Add support for the STM32MP25 SoC to the stm32-lptimer
- Add support for the STM32MP25 to the clocksource driver, handling
new register access requirements
- Add support for the STM32MP25 to the PWM driver, enabling up to two
PWM outputs

Broadcom BCM590xx:
- Add support for the BCM59054 PMU
- Parse the PMU ID and revision to support behavioral differences
between chip revisions
- Add regulator support for the BCM59054

Samsung S2MPG10:
- Add support for the S2MPG10 PMIC, which communicates via the
Samsung ACPM firmware instead of I2C

Exynos ACPM:
- Improve timeout detection reliability by using ktime APIs instead
of a loop counter assumption
- Allow PMIC access during late system shutdown by switching to
'udelay()' instead of a sleeping function
- Fix an issue where reading command results longer than 8 bytes
would fail
- Silence non-error '-EPROBE_DEFER' messages during boot to clean up
logs

Exynos LPASS:
- Fix an error handling path by switching to
'devm_regmap_init_mmio()' to prevent resource leaks
- Fix a bug where 'exynos_lpass_disable()' was called twice in the
remove function
- Fix another resource leak in the probe's error path by using
'devm_add_action_or_reset()'

Samsung SEC:
- Handle the s2dos05, which does not have IRQ support, explicitly to
prevent warnings
- Fix the core driver to correctly handle errors from
'sec_irq_init()' instead of ignoring them

STMPE-SPI:
- Correct an undeclared identifier in the 'MODULE_DEVICE_TABLE' macro

MAINTAINERS:
- Adjust a file path for the Siemens IPC LED drivers entry to fix a
broken reference

Maxim Drivers:
- Correct the spelling of "Electronics" in Samsung copyright headers
across multiple files

- Fix wakeup source memory leaks on device unbind for 88pm886,
as3722, max14577, max77541, max77705, max8925, rt5033, and
sprd-sc27xx drivers

Samsung SEC Drivers:
- Split the driver into a transport-agnostic core ('sec-core') and
transport-specific ('sec-i2c', 'sec-acpm') modules to support
non-I2C devices
- Merge the 'sec-core' and 'sec-irq' modules to reduce memory
consumption
- Move internal APIs to a private header to clean up the public API
- Improve code style by sorting includes, cleaning up headers,
sorting device tables, and using helper macros like
'dev_err_probe()', 'MFD_CELL', and 'REGMAP_IRQ_REG'
- Make regmap configuration for s2dos05/s2mpu05 explicit to improve
clarity
- Rework platform data and regmap instantiation to use OF match data
instead of a large switch statement

ROHM BD96801/2:
- Prepare the driver for new models by separating chip-specific data
into its own structure
- Drop IC name prefix from IRQ resource names in both the MFD and
regulator drivers for simplification

Broadcom BCM590xx:
- Refactor the regulator driver to store descriptions in a table to
ease support for new chips
- Rename BCM59056-specific data to prepare for the addition of other
regulators
- Use 'dev_err_probe()' for cleaner error handling

Exynos ACPM:
- Correct kerneldoc warnings and use the conventional 'np' argument
name

General MFD:
- Convert 'aat2870' and 'tps65010' to use the per-client debugfs
directory provided by the I2C core
- Convert 'sm501', 'tps65010' and 'ucb1x00' to use the new GPIO line
value setter callbacks
- Constify 'regmap_irq_chip' and other structures in '88pm886' to
move data to read-only sections

BCM590xx:
- Drop the unused "id" member from the 'bcm590xx' struct in
preparation for a replacement

Samsung SEC Core:
- Remove forward declarations for functions that no longer exist

SM501:
- Remove the unused 'sm501_find_clock()' function

New Compatibles:
- Google: Add a PMIC child node to the 'google,gs101-acpm-ipc'
binding
- ROHM: Add new bindings for 'rohm,bd96802-regulator' and
'rohm,bd96802-pmic', and add compatibles for BD96805 and BD96806
- Maxim: Add new bindings for 'maxim,max77759-gpio',
'maxim,max77759-nvmem', and the top-level 'maxim,max77759'
- STM: Add 'stm32mp25' compatible to the 'stm32-lptimer' binding

mfd: sec-i2c: s2dos05/s2mpu05: Use explicit regmap config and drop default

When support for PMICs without compatibles was removed in
commit f736d2c0caa8 ("mfd: sec: Remove PMICs without compatibles"

mfd: sec-i2c: s2dos05/s2mpu05: Use explicit regmap config and drop default

When support for PMICs without compatibles was removed in
commit f736d2c0caa8 ("mfd: sec: Remove PMICs without compatibles"),
sec_regmap_config effectively became an orphan, because S5M8763X was
the only user left of it before removal, using the default: case of the
switch statement.

When s2dos05 and s2mpu05 support was added in commit bf231e5febcf
("mfd: sec-core: Add support for the Samsung s2dos05") and commit
ed33479b7beb ("mfd: sec: Add support for S2MPU05 PMIC"), they ended up
using that orphaned regmap_config in a non-obvious way due to the
default: case of the device type switch matching statement taking
effect again.

To make things more obvious, and to help the reader of this code while
reasoning about what the intention might be here, and to ensure future
additions to support new devices in this driver don't forget to add a
regmap config, add an explicit regmap config for these two devices, and
completely remove the generic regmap config as it becomes an orphan
again that shouldn't be used by any device.

Note that this commit doesn't fix the issue that s2dos05_regmap_config
ands2mpu05_regmap_config really are incomplete, but I have no
documentation on them.

I2C-specific driver code into its own kernel module, sec-i2c, and

At the same time, update all defconfigs that reference the old kconfig
symbol name.

While at it, also update file header comments and module description(s)
to drop references to 'mfd', and update comments to be C-style, not
C++.
