mfd: maxim: Correct Samsung "Electronics" spelling in copyright headers (2025-06-03 09:46:41 +0100)
----------------------------------------------------------------
MFD for v6.16
* 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
* General:
* 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

* 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
* Broadcom: Add `bcm59054` compatible
* Atmel/Microchip: Add `microchip,sama7d65-gpbr` and `microchip,sama7d65-secumod` compatibles
