2024-11-12dt-bindings: mfd: Add Realtek RTL9300 switch peripheralsChris Packham
Add device tree schema for the Realtek RTL9300 switches. The RTL9300 family is made up of the RTL9301, RTL9302B, RTL9302C and RTL9303. These have the same SoC differ in the Ethernet switch/SERDES arrangement. Currently the only supported features are the syscon-reboot and i2c controllers. The syscon-reboot is needed to be able to reboot the board. The I2C controllers are slightly unusual because they each own an SCL pin (GPIO8 for the first controller, GPIO 17 for the second) but have 8 common SDA pins which can be assigned to either controller (but not both).

On some x86 Bay Trail tablets which shipped with Android as factory OS, the DSDT is so broken that the PMIC needs to be manually instantiated by the special x86-android-tablets.ko "fixup" driver for cases like this.

2024-11-01mfd: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/mfd to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. On the way do a few whitespace changes to make indention consistent.

2024-11-01mfd: rtc: bd7xxxx Drop IC name from IRQMatti Vaittinen
A few ROHM PMICs have an RTC block which can be controlled by the rtc-bd70528 driver. The RTC driver needs the alarm interrupt information from the parent MFD driver. The MFD driver provides the interrupt information as a set of named interrupts, where the name is of form: <PMIC model>-rtc-alm-<x>, where x is an alarm block number. >From the RTC driver point of view it is irrelevant what the PMIC name is. It is sufficient to know this is alarm interrupt for a block X. The PMIC model information is carried to RTC via the platform device ID. Hence, having the PMIC model in the interrupt name is only making things more complex because the RTC driver needs to request differently named interrupts on different PMICs, making code unnecessary complicated. Simplify this slightly by always using the RTC driver name 'bd70528' as the prefix for alarm interrupts, no matter what the exact PMIC model is, and always request the alarm interrupts of same name no matter what the PMIC model is.

2024-10-31mfd: cs42l43: Disable IRQs during suspendCharles Keepax
The ASoC CODEC driver masks the IRQs whilst entering and exiting system suspend to avoid issues where the IRQ handler can run but PM runtime is disabled. However, as the IRQs could also be used from other parts of the driver, it would be better to move this handling to the MFD level. Remove the handling from the ASoC driver and move it to the MFD driver. Whilst moving also ensure the IRQs are all masked at the device level before powering down the device, as per hardware recommendations.

2024-10-16mfd: intel_soc_pmic_bxtwc: Use IRQ domain for PMIC devicesAndy Shevchenko
While design wise the idea of converting the driver to use the hierarchy of the IRQ chips is correct, the implementation has (inherited) flaws. This was unveiled when platform_get_irq() had started WARN() on IRQ 0 that is supposed to be a Linux IRQ number (also known as vIRQ). Rework the driver to respect IRQ domain when creating each MFD device separately, as the domain is not the same for all of them.

2024-10-16mfd: cs42l43: Fix issues in probe error pathsCharles Keepax
The error path in cs42l43_boot_work() will lead to an unbalanced regulator put, when the driver is removed. Fix this by relying on remove to power down the device. Also the boot work needs to be synchronised with driver remove, to ensure the work is not still running after the driver has been removed. Add the required cancel_work_sync().
