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 -

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 -

mfd: sec-i2c: Rework platform data and regmap instantiatingInstead of a large open-coded switch statement, just add both regmapconfig and device type to the OF match data.

Wed, 09 Apr 2025 22:37:35 +0200

mfd: sec-i2c: s2dos05/s2mpu05: Use explicit regmap config and drop defaultWhen support for PMICs without compatibles was removed incommit f736d2c0caa8 ("mfd: sec: Remove PMICs without compatibles"),sec_regmap_config effectively became an orphan, because S5M8763X wasthe only user left of it before removal, using the default: case of theswitch statement.When s2dos05 and s2mpu05 support was added in commit bf231e5febcf("mfd: sec-core: Add support for the Samsung s2dos05") and commited33479b7beb ("mfd: sec: Add support for S2MPU05 PMIC"), they ended upusing that orphaned regmap_config in a non-obvious way due to thedefault: case of the device type switch matching statement takingeffect again.To make things more obvious, and to help the reader of this code whilereasoning about what the intention might be here, and to ensure futureadditions to support new devices in this driver don't forget to add aregmap config, add an explicit regmap config for these two devices, andcompletely remove the generic regmap config as it becomes an orphanagain that shouldn't be used by any device.Note that this commit doesn't fix the issue that s2dos05_regmap_configands2mpu05_regmap_config really are incomplete, but I have nodocumentation on them.Reviewed-by: Krzysztof Kozlowski Signed-off-by: André Draszik Link: https://lore.kernel.org/r/20250409-s2mpg10-v4-14-d66d5f39b6bf@linaro.orgSigned-off-by: Lee Jones List of files: /linux/drivers/mfd/sec-i2c.c

mfd: sec: Split into core and transport (i2c) driversAs a preparation for adding support for Samsung's S2MPG10, which isconnected via SPEEDY / ACPM rather than I2C, split out (move) allI2C-specific driver code into its own kernel module, sec-i2c, andmake the existing sec-core module be just the transport-agnostic coredriver kernel module.At the same time, update all defconfigs that reference the old kconfigsymbol 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, notC++.Reviewed-by: Krzysztof Kozlowski Signed-off-by: André Draszik Link: https://lore.kernel.org/r/20250409-s2mpg10-v4-8-d66d5f39b6bf@linaro.orgSigned-off-by: Lee Jones List of files: /linux/drivers/mfd/sec-i2c.c
