2019-05-14mfd: cros_ec: Instantiate properly CrOS Touchpad MCU deviceEnric Balletbo i Serra
Support Touchpad MCU as a special of CrOS EC devices. The current Touchpad MCU is used on Eve Chromebook and used the same protocol as other CrOS EC devices. When a MCU has touchpad support (aka EC_FEATURE_TOUCHPAD), it is instantiated as a special CrOS EC device with device name 'cros_tp'. So regardless of the probing order between the actual cros_ec and cros_tp, the userspace and other kernel drivers should not confuse them.

Support Fingerprint MCU as a special of CrOS EC devices. The current FP MCU uses the same EC SPI protocol v3 as other CrOS EC devices on a SPI bus. When a MCU has fingerprint support (aka EC_FEATURE_FINGERPRINT), it is instantiated as a special CrOS EC device with device name 'cros_fp'.

Update the feature enum for the Chromebook Embedded Controller to the latest version. Some of these enums are still not used in the kernel but we might be also interested on have these enums up to date. Userspace can use them to query the features to the EC via the cros-ec character device. While here, also fix a typo in one comment in the enum.

Mismatch between what is found in the Datasheets for DA9063 and DA9063L provided by Dialog Semiconductor, and the register names provided in the MFD registers file. The changes are for the OTP (one-time-programming) control registers. The two naming errors are OPT instead of OTP, and COUNT instead of CONT (i.e. control).

2019-05-14platform/chrome: Add support for v1 of host sleep eventEvan Green
Add support in code for the new forms of the host sleep event. Detects the presence of this version of the command at runtime, and use whichever form the EC supports. At this time, always request the default timeout, and only report the failing response via a WARN_ONCE(). Future versions could accept the sleep parameter from outside the driver, and return the response information to usermode or elsewhere.

Introduce the command and response structures for the second revision of the host sleep event. These structures are part of a new EC change that enables detection of failure to enter S0ix. The EC waits a kernel-specified timeout (or a default amount of time) for the S0_SLP pin to change, and wakes the system if that change does not occur in time.

2019-04-02mfd: altera-sysmgr: Add SOCFPGA System ManagerThor Thayer
The SOCFPGA System Manager register block aggregates different peripheral functions into one area. On 32 bit ARM parts, handle in the same way as syscon. 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.

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.

The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig:config MFD_WM8350 drivers/mfd/Kconfig: bool ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. We delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments. We replace module.h with init.h and export.h ; the latter since the file does export some symbols. Previous demodularizaion work has made wm8350_device_exit() no longer used, so it is also removed from the 8350 core code.

2019-01-09ACPI / PMIC: Add support for executing PMIC MIPI sequence elementsHans de Goede
DSI LCD panels describe an initialization sequence in the Video BIOS Tables using so called MIPI sequences. One possible element in these sequences is a PMIC specific element of 15 bytes. Although this is not really an ACPI opregion, the ACPI opregion code is the closest thing we have. We need to have support for these PMIC specific MIPI sequence elements somwhere. Since we already instantiate a special platform device for Intel PMICs for the ACPI PMIC OpRegion handler to bind to, with PMIC specific implementations of the OpRegion, the handling of MIPI sequence PMIC elements fits very well in the ACPI PMIC OpRegion code. This commit adds a new intel_soc_pmic_exec_mipi_pmic_seq_element() function, which is to be backed by a PMIC specific exec_mipi_pmic_seq_element callback. This function will be called by the i915 code to execture MIPI sequence PMIC elements.
