2022-12-08mfd: Drop obsolete dependencies on COMPILE_TESTJean Delvare1-8/+8
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.

2022-12-07mfd: intel_soc_pmic: Allow COMPILE_TEST or I2C_DESIGNWARE_PLATFORMRandy Dunlap1-1/+1
Linus expressed a desire to have intel_soc_pmic_crc.o (INTEL_SOC_PMIC, for Crystal Cove) be built on an "allmodconfig" build, when I2C_DESIGNWARE_PLATFORM=m, to enhance build test coverage. The PMIC driver won't work in this case since it requires I2C_DESIGNWARE_PLATFORM=y to operate properly, but adding "|| COMPILE_TEST" does improve the build test coverage.

2021-12-22platform/x86/intel: Move intel_pmt from MFD to Auxiliary BusDavid E. Box1-10/+0
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.

2021-06-02mfd: arizona: Allow building arizona MFD-core as moduleHans de Goede1-1/+1
There is no reason why the arizona core,irq and codec model specific regmap bits cannot be build as a module. All they do is export symbols which are used by the arizona-spi/i2c and arizona-codec modules, which themselves can be built as module. Change the Kconfig and Makefile arizona bits so that the arizona MFD-core can be built as a module. This is especially useful on x86 platforms with a WM5102 codec, this allows the arizona MFD driver necessary for the WM5102 codec to be enabled in generic distro-kernels without growing the base kernel-image size. Note this also adds an explicit "depends on MFD_ARIZONA" to all the arizona codec Kconfig options. The codec drivers use functions from mfd arizona-core. These new depends are necessary to disallow the codec drivers being builtin when the arizona-core is build as a module, otherwise we end up with missing symbol errors when building vmlinuz.

The ST-Ericsson ABX500 Mixed Signal IC family chips are only present on ST-Ericsson U8500 Series platforms. Hence add a dependency on ARCH_U8500, to prevent asking the user about this driver when configuring a kernel without U8500 support. Also, merely enabling CONFIG_COMPILE_TEST should not enable additional code, and thus should not enable this driver by default.
