This debugfs isn't used by anyone, if we want to dump the contents of registers we should just convert the driver to regmap instead. I'm also excluding this from the device tree bindings when converting to YAML because it is not a real device, and device trees should only contain real physical devices. Delete it.

2022-03-08mfd: ab8500: Rewrite bindings in YAMLLinus Walleij
This rewrites the former text based AB8500 bindings in YAML. When the AB8500 bindings were first written (in 2012) we were not strict on some things and node names were definitely not standardized. This patch uses standard node names to most of the subnodes on the AB8500 and is accompanied by another patch fixing all the DTS files to conform to this. The bindings are not as perfect as newly written bindings would be, it is a best effort to deal with the legacy.

2022-03-08mfd: stmfx: Improve error message triggered by regulator fault in .remove()Uwe Kleine-König
Returning a non-zero value in an i2c remove callback results in the i2c core emitting a very generic error message ("remove failed (-ESOMETHING), will be ignored") and as the message indicates not further error handling is done. Instead emit a more specific error message and then return zero in .remove(). The long-term goal is to make the i2c remove prototype return void, making all implementations return 0 is preparatory work for this change.

2022-03-08mfd: intel_soc_pmic_crc: Set main IRQ domain bus token to DOMAIN_BUS_NEXUSHans de Goede
For the CRC PMIC we end up with multiple IRQ domains with the same fwnode. One for the irqchip which demultiplexes the actual PMIC interrupt into interrupts for the various cells (known as the level 1 interrupts); And 2 more for the irqchips which are part of the crystal_cove_gpio and crystal_cove_charger cells. This leads to the following error being printed when CONFIG_GENERIC_IRQ_DEBUGFS is enabled: debugfs: File '\_SB.I2C7.PMIC' in directory 'domains' already present! Set the bus token of the main IRQ domain to DOMAIN_BUS_NEXUS to avoid this error, this also allows irq_find_matching_fwspec() to find the right domain if necessary. Note all 3 domain registering drivers need to set the IRQ domain bus token. This is necessary because the IRQ domain code defaults to creating the debugfs dir with just the fwnode name and then renames it when the bus token is set. So each one starts with the same default name and all 3 must be given a different name to avoid problems when one of the other drivers loads and starts with the same default name.

2022-03-08mfd: intel_soc_pmic_crc: Add crystal_cove_charger cell to BYT cellsHans de Goede
The Crystal Cove PMIC has a pin which can be used to connect the IRQ of an external charger IC. On some boards this is used and we need to have a cell for this, with a driver which creates its own irqchip with a single IRQ for the charger driver to consume. The charger driver cannot directly consume the IRQ from the MFD level irqchip because the PMIC has 2 levels of interrupts and the second level interrupt status register, which is handled by the cell drivers, needs to have the IRQ acked to avoid an IRQ storm.

2022-03-07watchdog: max77620: Add support for the max77714 variantLuca Ceresoli
The MAX77714 is a MFD chip whose watchdog has the same programming procedures as the MAX77620 watchdog, but most register offsets and bit masks are different, as well as some features. Support the MAX77714 watchdog by adding a variant description table holding the differences. All the features implemented by this driver are available on the MAX77714 except for the lack of a WDTOFFC bit. Instead of using a "HAS_*" flag we handle this by holding in the cnfg_glbl2_cfg_bits struct field the bits (i.e. the features) to enable in the CNFG_GLBL2 register. These bits differ among the two models. This implementation allows to avoid any conditional code, keeping the execution flow unchanged.

The MAX77714 RTC chip is explicitly set to 24-hour mode in max77686_rtc_probe() -> max77686_rtc_init_reg() and never changed back to 12-hour mode.

2022-02-14iio: temperature: iqs620at-temp: Add support for V3 siliconJeff LaBundy
The vendor introduced an updated revision of IQS620A(T) silicon which is backwards-compatible with previous revisions, the only exception being the offset used to derive temperature. Enable this new revision by returning the appropriate offset as a function of the hardware number provided by the parent MFD.

2022-02-14mfd: iqs62x: Provide device revision to sub-devicesJeff LaBundy
Individual sub-devices may elect to make decisions based on the specific revision of silicon encountered at probe. This data is already read from the device, but is not retained. Pass this data on to the sub-devices by adding the software and hardware numbers (registers 0x01 and 0x02, respectively) to the iqs62x_core struct.
