Linking a file into two modules can have unintended side-effects and produces a W=1 warning: scripts/Makefile.build:236: drivers/mfd/Makefile: rsmu_core.o is added to multiple modules: rsmu-i2c rsmu-spi Make this one a separate module instead.

The primary use of the CRC PMIC's PWM is for LCD panel backlight control by the i915 driver. Due to its complexity the probe() function of the i915 driver does not support -EPROBE_DEFER handling. So far the pwm-crc driver must be built into the kernel to ensure that the pwm_get() done by the i915 driver succeeds at once (rather then returning -EPROBE_DEFER). But the PWM core can load the module from pwm_get() if a module-name is provided in the pwm_lookup associated with the consumer device. Switch to using PWM_LOOKUP_WITH_MODULE() for the lookup added for the Intel integrated GPU, so that the PWM core can load the module from pwm_get() as needed allowing the pwm-crc driver to be safely built as module. This has been successfully tested on an Asus T100TAM with pwm-crc build as a module. Link: https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/11081Signed-off-by:

Add a new mediatek,mt8365-scpsys compatible, for the SCPSYS syscon block having power controller. Previously the DTS was re-using SYSCFG compatible, but that does not seem right, because SYSCFG does not have children. Signed-off-by:

These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove commas after the sentinel entries. Signed-off-by:

Introduce driver for WDG block on ROHM BD96801 scalable PMIC. This driver only supports watchdog with I2C feeding and delayed response detection. Whether the watchdog toggles PRSTB pin or just causes an interrupt can be configured via device-tree. The BD96801 PMIC HW supports also window watchdog (too early feeding detection) and Q&A mode. These are not supported by this driver. Signed-off-by:

The ROHM BD96801 "Scalable PMIC" is an automotive grade PMIC which can scale to different applications by allowing chaining of PMICs. The PMIC also supports various protection features which can be configured either to fire IRQs - or to shut down power outputs when failure is detected. The driver implements basic voltage control and sending error notifications. NOTE: The driver does not support doing configuration which require the PMIC to be in STBY state. The omitted feature set includes setting safety limit values, changing LDO voltages and controlling enable state for some regulators. Also, the ERRB IRQ is not handled. Signed-off-by:
