2020-04-15mfd: stmpe: Preparations for STMPE ADC driverStefan Agner
This prepares the MFD for the STMPE ADC driver. This commit introduces devicetree settings that are used by the ADC and adds an init function. Common ADC settings that are shared with the touchscreen driver can now reside in the overlying MFD.

2019-11-28mfd: max8997: Enale irq-wakeup unconditionallyMarek Szyprowski
[ Upstream commit efddff27c886e729a7f84a7205bd84d7d4af7336 ] IRQ wake up support for MAX8997 driver was initially configured by respective property in pdata. However, after the driver conversion to device-tree, setting it was left as 'todo'. Nowadays most of other PMIC MFD drivers initialized from device-tree assume that they can be an irq wakeup source, so enable it also for MAX8997. This fixes support for wakeup from MAX8997 RTC alarm.

2019-11-28mfd: mc13xxx-core: Fix PMIC shutdown when reading ADC valuesFabio Estevam
[ Upstream commit 55143439b7b501882bea9d95a54adfe00ffc79a3 ] When trying to read any MC13892 ADC channel on a imx51-babbage board: The MC13892 PMIC shutdowns completely. After debugging this issue and comparing the MC13892 and MC13783 initializations done in the vendor kernel, it was noticed that the CHRGRAWDIV bit of the ADC0 register was not being set. This bit is set by default after power on, but the driver was clearing it. After setting this bit it is possible to read the ADC values correctly.

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.

We can now select GPIOLIB and be done with it, for all archs. After some struggle it even work on UM. Not that it has GPIO, but if it wants to, it can select the library. - continued efforts to make drivers properly either tristate or bool. - introduce a warning for drivers assigning default triggers to their irqchip lines when probed from device tree, so we find and fix these ambigous drivers. It is agreed that in the OF config path, the device tree defines trigger characteristics. - the same warning, mutatis mutandis, for ACPI-probed GPIO irqchips. - we introduce the ability to mark certain IRQ lines as "unusable" as they can be taken by BIOS/firmware, unrouted in silicon and generally nasty if you use them, and such things. This is put to good use in the STMPE driver and also in the Cherryview pin control driver. - a new "mockup" virtual GPIO device that can be used for testing. The plan is to add unit tests under tools/* for exercising this device and verify that the kernel code paths are working as they should. - make memory-mapped I/O-drivers depend on HAS_IOMEM. This was implicit all the time, but when people started building UM with allyesconfig or allmodconfig it exploded in their face. - move some stray bits of device tree and ACPI HW description callbacks down into their respective implementation silo. These were causing issues when compiling on !HAS_IOMEM as well, so now eventually UM compiles the GPIOLIB library if it wants to. New drivers: - new driver for the Aspeed GPIO front-end companion to the pin controller merged through the pin control tree. - new driver for the LP873x PMIC GPIO portions. - new driver for Technologic Systems' I2C FPGA GPIO such as TS4900, TS-7970, TS-7990 and TS-4100. - new driver for the Broadcom BCM63xx series including BCM6338 and BCM6345. - new driver for the Intel WhiskeyCove PMIC GPIO. - new driver for the Allwinner AXP209 PMIC GPIO portions. - new driver for Diamond Systems 48 line GPIO-MM, another of these port-mapped I/O expansion cards. - support the STMicroelectronics STMPE1600 variant in the STMPE driver. Driver improvements: - the STMPE driver now supports rising/falling edge detection properly for IRQs. - the PCA954x will now fetch and enable its VCC regulator properly. - major rework of the PCA953x driver with the goal of eventually switching it over to use regmap and thus modernize it even more. - switch the IOP driver to use the generic MMIO GPIO library. - move the ages old HTC EGPIO (extended GPIO) GPIO expander driver over to this subsystem from MFD, achieveing some separation of concerns" * tag 'gpio-v4.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (81 commits) gpio: add missing static inline gpio: OF: localize some gpiochip init functions gpio: acpi: separation of concerns gpio: OF: separation of concerns gpio: make memory-mapped drivers depend on HAS_IOMEM gpio: stmpe: use BIT() macro gpio: stmpe: forbid unused lines to be mapped as IRQs mfd/gpio: Move HTC GPIO driver to GPIO subsystem gpio: MAINTAINERS: Add an entry for GPIO mockup driver gpio/mockup: add virtual gpio device gpio: Added zynq specific check for special pins on bank zero gpio: axp209: Implement get_direction gpio: aspeed: remove redundant return value check gpio: loongson1: remove redundant return value check ARM: omap2: fix missing include gpio: tc3589x: fix up complaints on unsigned gpio: tc3589x: add .get_direction() and small cleanup gpio: f7188x: use gpiochip_get_data instead of container_of gpio: tps65218: use devm_gpiochip_add_data() for gpio registration gpio: aspeed: fix return value check in aspeed_gpio_probe() ...

2016-10-04mfd: ab8500-debugfs: Prevent initialised field from being over-writtenLee Jones
Due to the lack of parity in the way array fields have been named/ numbered, a mistake was made where more debug fields were declared than actually existed. In doing so, 2 fields were added, which although unclear, were already declared in the array. The result was that the latter declarations trashed the former ones. This patch places the array back in the correct order and removes the offending NULL entries. While we're at it, let's ensure this doesn't happen again by naming each field properly and add a new *_LAST define to describe how many fields there should be.

This patch adds common driver for the Top block of the Samsung Exynos SoC Low Power Audio Subsystem. This is a minimal driver which prepares resources for IP blocks like I2S, audio DMA and UART and exposes a regmap for the Top block registers. Also system power ops are added to ensure the Audio Subsystem is operational after system suspend/resume cycle.

2016-10-04mfd: 88pm80x: Double shifting bug in suspend/resumeDan Carpenter
set_bit() and clear_bit() take the bit number so this code is really doing "1 << (1 << irq)" which is a double shift bug. It's done consistently so it won't cause a problem unless "irq" is more than 4.

2016-10-04mfd: arizona: Add gating of external MCLKn clocksSylwester Nawrocki
This patch adds requesting of the clocks supplied on MCLK1, MCLK2 pins, gating of the 32k clock is added to the arizona_clk32k_enable(), arizona_clk32k_disable() helpers. It's a temporary change until the CODEC's clock controller gets exposed through the clk API and is helpful for board configurations where the MCLK clocks are not provided by always on oscillators.

2016-09-13mfd: axp20x: Add support for AXP806 PMICChen-Yu Tsai
The X-Powers AXP806 is a new PMIC that is paired with Allwinner's A80 SoC, along with a master AXP809 PMIC. This PMIC has a new register layout, and supports some functions not seen in other X-Powers PMICs, such as master-slave mode, or having multiple AXP806 PMICs on the same bus with address space extension, or supporting both I2C and RSB mode. I2C has not been tested. This patch adds support for the interrupts of the PMIC. A regulator sub-device is enabled, but actual regulator support will come in a later patch.

2016-08-31mfd: cros_ec: Add MKBP event supportVic Yang
Newer revisions of the ChromeOS EC add more events besides the keyboard ones. So handle interrupts in the MFD driver and let consumers register for notifications for the events they might care. To keep backward compatibility, if the EC doesn't support MKBP event, we fall back to the old MKBP key matrix host command.

2016-08-21iio: adc: ti_am335x_adc: Increase timeout value waiting for ADC sampleVignesh R
Now that open delay and sample delay for each channel is configurable via DT, the default IDLE_TIMEOUT value is not enough as this is calculated based on hardcoded macros. This results in driver returning EBUSY sometimes. Fix this by increasing the timeout value based on maximum value possible to open delay and sample delays for each channel.
