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.

2021-12-22platform/x86/intel: Move intel_pmt from MFD to Auxiliary BusDavid E. Box1-1/+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 Goede1-7/+7
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.

For the moment this driver only supports Regulator, Poweroff and Onkey functionalities for the ATC2603C and ATC2609A chip variants. Since the PMICs can be accessed using both I2C and SPI buses, the following driver structure has been adopted: -----> atc260x-core.c (Implements core functionalities) / ATC260x --------> atc260x-i2c.c (Implements I2C interface) \ -----> atc260x-spi.c (Implements SPI interface - TODO) Co-developed-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> Signed-off-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> Signed-off-by: Cristian Ciocaltea <cristian.ciocaltea@gmail.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
