| * mfd: pm8008: Add driver for QCOM PM8008 PMICGuru Das Srinagesh2021-06-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Qualcomm Technologies, Inc. PM8008 is a dedicated camera PMIC that integrates all the necessary power management, housekeeping, and interface support functions into a single IC. Its key features include overtemperature protection, low-dropout linear regulators, GPIOs, and an I2C interface. Add an MFD driver to support it.

| * mfd: arizona: Allow building arizona MFD-core as moduleHans de Goede2021-06-021-7/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intel Moorestown and Medfield are quite old Intel Atom based 32-bit platforms, which were in limited use in some Android phones, tablets and consumer electronics more than eight years ago. There are no bugs or problems ever reported outside from Intel for breaking any of that platforms for years. It seems no real users exists who run more or less fresh kernel on it. Commit 05f4434bc130 ("ASoC: Intel: remove mfld_machine") is also in align with this theory. Due to above and to reduce a burden of supporting outdated drivers, remove the support for outdated platforms completely.

| | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | 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.

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.

* / platform/x86: intel_pmc_ipc: Convert to MFDMika Westerberg2020-04-241-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | 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.

| * mfd: Add support for Merrifield Basin Cove PMICAndy Shevchenko2019-09-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add an MFD driver for Intel Merrifield Basin Cove PMIC. Firmware on the platforms which are using Basin Cove PMIC is "smarter" than on the rest supported by vanilla kernel. It handles first level of interrupt itself, while others do it on OS level. The driver is done in the same way as the rest of Intel PMIC MFD drivers in the kernel to support the initial design. The design allows to use one driver among few PMICs without knowing implementation details of the each hardware version or generation.

On 64 bit ARM parts, the System Manager can only be accessed by EL3 secure mode. Since a SMC call to EL3 is required, this new driver uses regmaps similar to syscon to handle the SMC call. Since regmaps abstract out the underlying register access, the changes to drivers accessing the System Manager are minimal.

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.
