When we consider MFD which implements hotplug (e.g. USB hotplug driver based on product and vendor IDs) functionality it turns out that its sub-devices are correctly matched with corresponding device tree nodes only at the first time. When physical device reboots or is replugged (and MFD driver is disconnected and probed back again) all sub-devices fails in mfd_add_device() with error 'Failed to locate of_node'. The reason of that behavior is that when any MFD sub-device is created for the first time (and matched with device tree node) it is added to the mfd_of_node_list. It looks like this list is never cleaned even if devices added there are intentionally removed from the system. So when MFD device is replugged and all sub-devices are matched with their device tree nodes again they fail as matched nodes already exist in mfd_of_node_list. In other words current implementation does not support MFD with hotplug feature. This commit extends MFD core for hotplugging support by removing appropriate OF node entry from mfd_of_node_list when corresponding device is removed from the system. Thanks to that when device is added once again it can be matched with its device tree node successfully. Signed-off-by:

In lp8788_irq_init(), if an error occurs after a successful irq_domain_add_linear() call, it must be undone by a corresponding irq_domain_remove() call. irq_domain_remove() should also be called in lp8788_irq_exit() for the same reason. Fixes: eea6b7cc ("mfd: Add lp8788 mfd driver") Signed-off-by:

If devm_of_platform_populate() fails, some resources need to be released.

AXP228 is a PMIC used on boards such as the Clockwork ClockworkPi and DevTerm. Its register map appears to be identical to the AXP221 variant. The only known difference is in the default values for regulator on/off states and voltages. Signed-off-by:

This adds support for the MediaTek MT6370 SubPMIC. MediaTek MT6370 is a SubPMIC consisting of a single cell battery charger with ADC monitoring, RGB LEDs, dual channel flashlight, WLED backlight driver, display bias voltage supply, one general purpose LDO, and the USB Type-C & PD controller complies with the latest USB Type-C and PD standards.

To reflect the point that this driver is only for one type of the PMICs, replace intel_soc_pmic with crystal_cove (avoid using crc for possible namespace collisions with CRC library APIs). Note, also rename the driver name since we don't expect any user that enumerates by it, only ACPI known so far. Signed-off-by:

The driver depends on ACPI, ACPI_PTR() resolution is always the same. Otherwise a compiler may produce a warning. That said, the rule of thumb either ugly ifdeffery with ACPI_PTR or none should be used in a driver. Signed-off-by:

Use sub-function of_compatible during probe, instead of using the node name. The code should not rely on the node names during probe, in addition to that the previously hard-coded node names are not compliant to the latest naming convention (they are not generic and they use underscores), and it was broken by mistake already once [1].

The VSC7512 is a networking chip that contains several peripherals. Many of these peripherals are currently supported by the VSC7513 and VSC7514 chips, but those run on an internal CPU. The VSC7512 lacks this CPU, and must be controlled externally. Utilize the existing drivers by referencing the chip as an MFD. Add support for the two MDIO buses, the internal phys, pinctrl, and serial GPIO. Signed-off-by:

As the commit message suggests, this simply adds the ability to select SGPIO pinctrl as a module. This becomes more practical when the SGPIO hardware exists on an external chip, controlled indirectly by I2C or SPI. This commit enables that level of control. Signed-off-by:

Several ocelot-related modules are designed for MMIO / regmaps. As such, they often use a combination of devm_platform_get_and_ioremap_resource() and devm_regmap_init_mmio(). Operating in an MFD might be different, in that it could be memory mapped, or it could be SPI, I2C... In these cases a fallback to use IORESOURCE_REG instead of IORESOURCE_MEM becomes necessary. When this happens, there's redundant logic that needs to be implemented in every driver. In order to avoid this redundancy, utilize a single function that, if the MFD scenario is enabled, will perform this fallback logic. Signed-off-by:
