2020-04-24platform/x86: intel_pmc_ipc: Convert to MFDMika Westerberg15-720/+602
This driver only creates a bunch of platform devices sharing resources belonging to the PMC device. This is pretty much what MFD subsystem is for so move the driver there, renaming it to intel_pmc_bxt.c which should be more clear what it is. MFD subsystem provides nice helper APIs for subdevice creation so convert the driver to use those. Unfortunately the ACPI device includes separate resources for most of the subdevices so we cannot simply call mfd_add_devices() to create all of them but instead we need to call it separately for each device. The new MFD driver continues to expose two sysfs attributes that allow userspace to send IPC commands to the PMC/SCU to avoid breaking any existing applications that may use these. Generally this is bad idea so document this in the ABI documentation.

2020-04-24platform/x86: intel_scu_ipc: Introduce new SCU IPC APIMika Westerberg3-61/+252
The current SCU IPC API has been operating on a single instance and there has been no way to pin the providing module in place when the SCU IPC is in use. This implements a new API that takes the SCU IPC instance as first parameter (NULL means the single instance is being used). The SCU IPC instance can be retrieved by calling new function intel_scu_ipc_dev_get() that take care of pinning the providing module in place as long as intel_scu_ipc_dev_put() is not called. The old API is updated to call the new API and is is left there in the legacy API header to support the existing users that cannot be converted easily. Subsequent patches will convert most of the users over to the new API.

2020-04-24platform/x86: intel_scu_ipc: Split out SCU IPC functionality from the SCU driverMika Westerberg7-68/+208
The SCU IPC functionality is usable outside of Intel MID devices. For example modern Intel CPUs include the same thing but now it is called PMC (Power Management Controller) instead of SCU. To make the IPC available for those split the driver into core part (intel_scu_ipc.c) and the SCU PCI driver part (intel_scu_pcidrv.c) which then calls the former before it goes and creates rest of the SCU devices. The SCU IPC will also register a new class that gets assigned to the device that is created under the parent PCI device. We also split the Kconfig symbols so that INTEL_SCU_IPC enables the SCU IPC library and INTEL_SCU_PCI the SCU driver and convert the users accordingly. While there remove default y from the INTEL_SCU_PCI symbol as it is already selected by X86_INTEL_MID.

This sorts the actual field names too, potentially causing even more chaos and confusion at merge time if you have edited the MAINTAINERS file.

They are all supposed to be sorted, but people who add new entries don't always know the alphabet. Plus sometimes the entry names get edited, and people don't then re-order the entry. Let's see how painful this will be for merging purposes (the MAINTAINERS file is often edited in various different trees), but Joe claims there's relatively few patches in -next that touch this, and doing it just before -rc1 is likely the best time. Fingers crossed. This was scripted with /scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS but then I also ended up manually upper-casing a few entry names that stood out when looking at the end result.
