2024-11-12mfd: intel_soc_pmic_crc: Add support for non ACPI instantiated i2c_clientHans de Goede
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. Add an i2c_device_id table so that the driver can match on manually instantiated i2c_client-s (which lack an ACPI fwnode to match on).

2024-11-12mfd: intel_soc_pmic_*: Consistently use filename as driver nameHans de Goede
Currently the intel_soc_pmic_bxtwc, intel_soc_pmic_chtwc and intel_soc_pmic_crc PMIC drivers use more or less free form strings for their driver name. Where as intel_soc_pmic_chtdc_ti and intel_soc_pmic_mrfld use the driver's filename as driver name. Update the 3 others to also use the driver's filename to make the naming consistent.

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: bd96801: Add ERRB IRQMatti Vaittinen
The ROHM BD96801 "scalable PMIC" provides two physical IRQs. The ERRB handling can in many cases be omitted because it is used to inform fatal IRQs, which usually kill the power from the SOC. There may however be use-cases where the SOC has a 'back-up' emergency power source which allows some very short time of operation to try to gracefully shut down sensitive hardware. Furthermore, it is possible the processor controlling the PMIC is not powered by the PMIC. In such cases handling the ERRB IRQs may be beneficial. Add support for ERRB IRQs.

2024-10-16mfd: syscon: Use regmap max_register_is_0 as neededNishanth Menon
syscon has always set the optional max_register configuration of regmap to ensure the correct checks are in place. However, a recent commit 0ec74ad3c157 ("regmap: rework ->max_register handling") introduced explicit configuration in regmap framework for register maps that is exactly 1 register, when max_register is pointing to a valid register 0. This commit solved a previous limitation of regmap framework. Update syscon driver to consistent in regmap configuration for all sizes of syscons by using this new capability by setting max_register_is_0, when the max_register is valid and 0.

2024-10-09mfd: Add Congatec Board Controller driverThomas Richard
Add core MFD driver for the Board Controller found on some Congatec SMARC module. This Board Controller provides functions like watchdog, GPIO, and I2C busses. This commit adds support only for the conga-SA7 module.

2024-09-23mfd: tc3589x: Drop vendorless compatible string from match tableRob Herring (Arm)
There's no need to list "tc3589x" in the DT match table. The I2C core will strip any vendor prefix and match against the i2c_device_id table which has an "tc3589x" entry. Probably "tc3589x" and TC3589X_UNKNOWN could be removed altogether. Use of that compatible was only on some STE platforms and was dropped in 2013. There were ABI breaks in 2014 claiming no DTs in the wild. See commit 1637d480f873 ("pinctrl: nomadik: force-convert to generic config bindings").

There are 2G and 4G RAM versions of the Lenovo Yoga Tab 3 X90F and it turns out that the 2G version has a DMI product name of "CHERRYVIEW D1 PLATFORM" where as the 4G version has "CHERRYVIEW C0 PLATFORM". The sys-vendor + product-version check are unique enough that the product-name check is not necessary. Drop the product-name check so that the existing DMI match for the 4G RAM version also matches the 2G RAM version.
