2014-01-21mfd: Add LP3943 MFD driverMilo Kim
LP3943 has 16 output pins which can be used as GPIO expander and PWM generator. * Regmap I2C interface for R/W LP3943 registers * Atomic operations for output pin assignment The driver should check whether requested pin is available or not. If the pin is already used, pin request returns as a failure. A driver data, 'pin_used' is checked when gpio_request() and pwm_request() are called. If the pin is available, then pin_used is set. And it is cleared when gpio_free() and pwm_free(). * Device tree support Compatible strings for GPIO and PWM driver. LP3943 platform data is PWM related, so parsing the device tree is implemented in the PWM driver. Signed-off-by: Milo Kim <milo.kim@ti.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

There is no reason for ssbi to have its own top-level driver directory when the only users of this interface are all MFD drivers. The only mainline driver using it at the moment (PM8921) is marked broken and in fact does not compile.

2012-11-05mfd: Versatile Express system registers driverPawel Moll
This is a platform driver for Versatile Express' "system register" block. It's a random collection of registers providing the following functionality: - low level platform functions like board ID access; in order to use those, the driver must be initialized early, either statically or based on the DT - config bus bridge via "system control" interface; as the response from the controller does not generate interrupt (yet), the status register is periodically polled using a timer - pseudo GPIO lines providing MMC card status and Flash WP# signal control - LED interface for a set of 8 LEDs on the motherboard, with "heartbeat", "mmc0" and "cpu0" to "cpu5" as default triggers Signed-off-by: Pawel Moll <pawel.moll@arm.com>
2012-11-05mfd: Versatile Express config infrastructurePawel Moll
Versatile Express platform has an elaborated configuration system, consisting of microcontrollers residing on the mother- and daughterboards known as Motherboard/Daughterboard Configuration Controller (MCC and DCC). The controllers are responsible for the platform initialization (reset generation, flash programming, FPGA bitfiles loading etc.) but also control clock generators, voltage regulators, gather environmental data like temperature, power consumption etc. Even the video output switch (FPGA) is controlled that way. Those devices are _not_ visible in the main address space and the usual communication channel uses some kind of a bridge in the peripheral block sending commands (requests) to the controllers and receiving responses. It can take up to 500 microseconds for a transaction to be completed, therefore it is important to provide a non-blocking interface to it. This patch adds an abstraction of this infrastructure. Bridge drivers can register themselves with the framework. Then, a driver of a device can request an abstract "function" - the request will be redirected to a bridge referred by thedd "arm,vexpress,config-bridge" property of the device tree node.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/misc into for-next mfd: Initial support for Wolfson Arizona platform and WM5102 devices The Wolfson Arizona platform is used to provide common register interface to a series of low power audio hub CODECs, starting with the WM5102. Since the features of these devices work over a range of subsystems an MFD core driver is provided to instantiate the subdevices and arbitrate access between them. As the new regmap wake IRQ functionality is used as part of the driver it is incorporated as a dependency.
2012-07-09mfd: Add Maxim 77686 driverJonghwa Lee
This patch is device driver for MAX77686 chip. MAX77686 is PMIC and includes regulator and rtc on it. This driver is core of MAX77686 chip, so provides common support for accessing on-chip devices. It uses irq_domain to manage irq and regmap to read/write data to its register with i2c bus.

Pull first batch of arm-soc cleanups from Olof Johansson: "These cleanups are basically all over the place. The idea is to collect changes with minimal impact but large number of changes so we can avoid them from distracting in the diffstat in the other series. A significant number of lines get removed here, in particular because the ixp2000 and ixp23xx platforms get removed. These have never been extremely popular and have fallen into disuse over time with no active maintainer taking care of them. The u5500 soc never made it into a product, so we are removing it from the ux500 platform. Many good cleanups also went into the at91 and omap platforms, as has been the case for a number of releases."

2012-05-20mfd: Remove confusing ab8500-i2c file and merge into ab8500-coreLee Jones
ab8500-i2c is used as core code to register the ab8500 device. After allocating ab8500 memory, it immediately calls into ab8500-core where the real initialisation takes place. This patch moves all core registration and memory allocation into the true ab8500-core file and removes ab8500-i2c completely.
