2020-11-04mfd: Intel Platform Monitoring Technology supportDavid E. Box
Intel Platform Monitoring Technology (PMT) is an architecture for enumerating and accessing hardware monitoring facilities. PMT supports multiple types of monitoring capabilities. This driver creates platform devices for each type so that they may be managed by capability specific drivers (to be introduced). Capabilities are discovered using PCIe DVSEC ids. Support is included for the 3 current capability types, Telemetry, Watcher, and Crashlog. The features are available on new Intel platforms starting from Tiger Lake for which support is added. This patch adds support for Tiger Lake (TGL), Alder Lake (ADL), and Out-of-Band Management Services Module (OOBMSM). Also add a quirk mechanism for several early hardware differences and bugs. For Tiger Lake and Alder Lake, do not support Watcher and Crashlog capabilities since they will not be compatible with future product. Also, fix use a quirk to fix the discovery table offset.

2020-09-30mfd: intel-m10-bmc: Add Intel MAX 10 BMC chip support for Intel FPGA PACXu Yilun
This patch implements the basic functions of the BMC chip for some Intel FPGA PCIe Acceleration Cards (PAC). The BMC is implemented using the Intel MAX 10 CPLD. This BMC chip is connected to the FPGA by a SPI bus. To provide direct register access from the FPGA, the "SPI slave to Avalon Master Bridge" (spi-avmm) IP is integrated in the chip. It converts encoded streams of bytes from the host to the internal register read/write on the Avalon bus. So This driver uses the regmap-spi-avmm for register accessing.

This driver provides access to the EC RAM of said embedded controller attached to the I2C bus as well as optionally supporting its slightly weird power-off/restart protocol. A particular implementation of the EC firmware can be identified by a model byte. If this driver identifies the Dell Ariel platform, it registers the appropriate cells.

2020-09-17mfd: Add simple regmap based I2C driverMichael Walle
There are I2C devices which contain several different functions but doesn't require any special access functions. For these kind of drivers an I2C regmap should be enough. Create an I2C driver which creates an I2C regmap and enumerates its children. If a device wants to use this as its MFD core driver, it has to add an individual compatible string. It may provide its own regmap configuration. Subdevices can use dev_get_regmap() on the parent to get their regmap instance.

2020-04-24platform/x86: intel_pmc_ipc: Convert to MFDMika Westerberg
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.

2019-10-18mfd: Switch the AB8500 GPADC to IIOLinus Walleij
The AB8500 GPADC driver is indeed a "general purpose ADC" driver, and while the IIO subsystem did not exist when the driver was first merged, it is never too late to clean things up and move it to the right place. Nowadays IIO provides the right abstractions and interfaces to do generic ADC work in the kernel. We have to cut a bunch of debugfs luggage to make this transition swift, but all these files to is read out the raw values of the ADC and the IIO subsystem already has a standard sysfs ABI for doing exactly this: no debugfs is needed.

2019-02-07mfd: lochnagar: Add support for the Cirrus Logic LochnagarCharles Keepax
Lochnagar is an evaluation and development board for Cirrus Logic Smart CODEC and Amp devices. It allows the connection of most Cirrus Logic devices on mini-cards, as well as allowing connection of various application processor systems to provide a full evaluation platform. This driver supports the board controller chip on the Lochnagar board. Audio system topology, clocking and power can all be controlled through the Lochnagar controller chip, allowing the device under test to be used in a variety of possible use cases. As the Lochnagar is a fairly complex device this MFD driver allows the drivers for the various features to be bound in. Initially clocking, regulator and pinctrl will be added as these are necessary to configure the system. But in time at least audio and voltage/current monitoring will also be added.

There are some cros-ec transport drivers (I2C, SPI) living in MFD, while others (LPC) living in drivers/platform. The transport drivers are more platform specific. So, move the I2C and SPI transport drivers to the platform/chrome directory. The patch also removes the MFD_ prefix of their Kconfig symbols.
