2020-05-20mfd: Add Gateworks System Controller core driverTim Harvey3-0/+293
The Gateworks System Controller (GSC) is an I2C slave controller implemented with an MSP430 micro-controller whose firmware embeds the following features: - I/O expander (16 GPIO's) using PCA955x protocol - Real Time Clock using DS1672 protocol - User EEPROM using AT24 protocol - HWMON using custom protocol - Interrupt controller with tamper detect, user pushbotton - Watchdog controller capable of full board power-cycle - Power Control capable of full board power-cycle see http://trac.gateworks.com/wiki/gsc for more details Signed-off-by: Tim Harvey <tharvey@gateworks.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2020-04-24platform/x86: intel_pmc_ipc: Convert to MFDMika Westerberg3-1/+484
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.

Convert the Intel Broxton Whiskey Cover PMIC driver to use the new SCU IPC API. This allows us to get rid of the PMC IPC implementation which is now covered in SCU IPC driver. We drop the error log if the IPC command fails because intel_scu_ipc_dev_command() does that already. Also move PMIC specific IPC message constants to the PMIC driver from the intel_pmc_ipc.h header.

2020-04-24platform/x86: intel_scu_ipc: Split out SCU IPC functionality from the SCU driverMika Westerberg1-2/+2
The SCU IPC functionality is usable outside of Intel MID devices. For example modern Intel CPUs include the same thing but now it is called PMC (Power Management Controller) instead of SCU. To make the IPC available for those split the driver into core part (intel_scu_ipc.c) and the SCU PCI driver part (intel_scu_pcidrv.c) which then calls the former before it goes and creates rest of the SCU devices. The SCU IPC will also register a new class that gets assigned to the device that is created under the parent PCI device. We also split the Kconfig symbols so that INTEL_SCU_IPC enables the SCU IPC library and INTEL_SCU_PCI the SCU driver and convert the users accordingly. While there remove default y from the INTEL_SCU_PCI symbol as it is already selected by X86_INTEL_MID.

Intel Elkhart Lake LPSS I2C has 100 MHz input clock instead of 133 MHz that was our preliminary information. This will result slower I2C bus clock when driver calculates its timing parameters in case ACPI tables don't provide them. Slower I2C bus clock is allowed but let's fix this to match with reality. While at it, keep the same default I2C device properties as Intel Broxton since it is not known do they need any update.

While the commit 2b8bd606b1e6 ("mfd: dln2: More sanity checking for endpoints") tries to harden the sanity checks it made at the same time a regression, i.e. mixed in and out endpoints. Obviously it should have been not tested on real hardware at that time, but unluckily it didn't happen. So, fix above mentioned typo and make device being enumerated again. While here, introduce an enumerator for magic values to prevent similar issue to happen in the future.

RK805 has the same kind of dual-role sleep/shutdown pin as RK809/RK817, so it makes little sense for the driver to have to have two completely different mechanisms to handle essentially the same thing.

2020-03-30mfd: rk808: Stop using syscore opsRobin Murphy1-14/+12
Setting the SLEEP pin to its shutdown function for appropriate PMICs doesn't need to happen in single-CPU context, so there's really no point involving the syscore machinery. Hook it up to the standard driver model shutdown method instead. This also obviates the issue that the syscore ops weren't being unregistered on probe failure or module removal.

2020-03-30mfd: rk808: Ensure suspend/resume hooks always workRobin Murphy1-2/+2
The RK809/RK817 suspend/resume hooks should not have to depend on whether this driver owns the pm_power_off hook, and thus the global rk808_i2c_client is set - indeed, the GPIO-based control is really only relevant when PSCI firmware is in charge of power rather than the kernel. As driver model callbacks, they have an appropriate device argument to hand, so can just always use that.

2020-03-30mfd: rk808: Always use poweroff when requestedSoeren Moch1-9/+2
With the device tree property "rockchip,system-power-controller" we explicitly request to use this PMIC to power off the system. So always register our poweroff function, even if some other handler (probably PSCI poweroff) was registered before. This does tend to reveal a warning on shutdown due to the Rockchip I2C driver not implementing an atomic transfer method, however since the write to DEV_OFF takes effect immediately the I2C completion interrupt is moot anyway, and as the very last thing written to the console it is only visible to users going out of their way to capture serial output.

2020-03-30mfd: pm8xxx: Replace zero-length array with flexible-array memberGustavo A. R. Silva1-1/+1
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

Add the cros-usbpd-notify driver as a subdevice on platforms that support the EC_FEATURE_USB_PD EC feature flag and don't have the ACPI PD notification device defined. This driver allows other cros-ec devices to receive PD event notifications from the Chrome OS Embedded Controller (EC) via a notification chain.

The watchdog driver compatible is "dlg,da9062-watchdog" and not "dlg,da9062-wdt". Therefore the mfd-core can't populate the of_node and fwnode. As result the watchdog driver can't parse the devicetree.

2020-01-24mfd: madera: Allow more time for hardware resetCharles Keepax1-8/+8
Both manual and power on resets have a brief period where the chip will not be accessible immediately afterwards. Extend the time allowed for this from a minimum of 1mS to 2mS based on newer evaluation of the hardware and ensure this reset happens in all reset conditions. Whilst making the change also remove the redundant NULL checks in the reset functions as the GPIO functions already check for this.

2020-01-24mfd: Kconfig: Rename Samsung to lowercaseKrzysztof Kozlowski1-1/+1
Fix up inconsistent usage of upper and lowercase letters in "Samsung" name. "SAMSUNG" is not an abbreviation but a regular trademarked name. Therefore it should be written with lowercase letters starting with capital letter. Although advertisement materials usually use uppercase "SAMSUNG", the lowercase version is used in all legal aspects (e.g. on Wikipedia and in privacy/legal statements on https://www.samsung.com/semiconductor/privacy-global/).

On AXP288 and newer PMICs, bit 7 of AXP20X_VBUS_IPSOUT_MGMT can be set to prevent using the VBUS input. However, when the VBUS unplugged and plugged back in, the bit automatically resets to zero. We need to set the register as volatile to prevent regmap from caching that bit. Otherwise, regcache will think the bit is already set and not write the register.

2020-01-24mfd: ab8500-core: Add device tree support for AB8505Stephan Gerhold2-8/+32
AB8505 support was never fully converted to the device tree. Most of the MFD cells for AB8505 lack an "of_compatible", which prevents them from being configured through the device tree. Align the definition of the AB8505 MFD cells with the ones for AB8500, and add device tree compatibles. Except for GPIO and regulators the compatibles are equal to those used for AB8500 because the hardware does not differ much. Finally, change db8500_prcmu_register_ab8500() to check for the AB8505 device tree node additionally, and probe it if it is found.
