Implement a regulator driver with IRQ support for fault management. Written against documentation [1] and [2] and tested on real hardware. Every channel has it's own regulator supply nammed 'vss1-supply' and 'vss2-supply'. The regulator supply is used to determine the output voltage, as the smart switch provides no output regulation.

Add the mfd driver for the Platform Management Component Interface (PMCI) based interface of Intel MAX10 BMC controller. PMCI is a software-visible interface, connected to card BMC which provided the basic functionality of read/write BMC register. The access to the register is done indirectly via a hardware controller/bridge that handles read/write/clear commands and acknowledgments for the commands. Previously, intel-m10-bmc provided sysfs under /sys/bus/spi/devices/... which is generalized in this change because not all MAX10 BMC appear under SPI anymore.

2022-12-08mfd: Drop obsolete dependencies on COMPILE_TESTJean Delvare
Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues. As a minor optimization, this also lets us drop of_match_ptr(), as we now know what it will resolve to, we might as well save cpp some work.

It also fixes a potential issue seen when SPI BAR is 64-bit. The current code works if and only if the PCI BAR of the hidden device is inside 4G address space. In case when firmware decides to go above 4G, we will get a wrong address.

2021-12-22platform/x86/intel: Move intel_pmt from MFD to Auxiliary BusDavid E. Box
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.
