[ Upstream commit c879a8c39dd55e7fabdd8d13341f7bc5200db377 ] 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.

mfd: intel_soc_pmic_crc: Merge Intel PMIC core to crc

2022-09-28T15:09:48+00:00

The core part is misleading since its only purpose to serve Crystal Cove PMIC, although for couple of different platforms. Merge core part into crc one. Advantages among others are: - speed up a compilation and build - decreasing the code base - reducing noise in the namespace by making some data static and const Signed-off-by: Andy Shevchenko Tested-by: Hans de Goede Reviewed-by: Hans de Goede Signed-off-by: Lee Jones Link: https://lore.kernel.org/r/20220801114211.36267-2-andriy.shevchenko@linux.intel.com

mfd: ocelot: Add support for the vsc7512 chip via spi

2022-09-09T06:54:47+00:00

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.

mfd: ab8500: Drop debugfs module

2022-03-08T09:44:06+00:00

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.

platform/x86/intel: Move intel_pmt from MFD to Auxiliary Bus

2021-12-22T12:56:19+00:00

Intel Platform Monitoring Technology (PMT) support is indicated by presence of an Intel defined PCIe Designated Vendor Specific Extended Capabilities (DVSEC) structure with a PMT specific ID. The current MFD implementation creates child devices for each PMT feature, currently telemetry, watcher, and crashlog. However DVSEC structures may also be used by Intel to indicate support for other features. The Out Of Band Management Services Module (OOBMSM) uses DVSEC to enumerate several features, including PMT. In order to support them it is necessary to modify the intel_pmt driver to handle the creation of the child devices more generically. To that end, modify the driver to create child devices for any VSEC/DVSEC features on supported devices (indicated by PCI ID). Additionally, move the implementation from MFD to the Auxiliary bus. VSEC/DVSEC features are really multifunctional PCI devices, not platform devices as MFD was designed for. Auxiliary bus gives more flexibility by allowing the definition of custom structures that can be shared between associated auxiliary devices and the parent device. Also, rename the driver from intel_pmt to intel_vsec to better reflect the purpose. This series also removes the current runtime pm support which was not complete to begin with. None of the current devices require runtime pm. However the support will be replaced when a device is added that requires it. Reviewed-by: Mark Gross Acked-by: Hans de Goede Signed-off-by: David E.
