2011-03-15mfd: add driver for sequencer serial portCyril Chemparathy
TI's sequencer serial port (TI-SSP) is a jack-of-all-trades type of serial port device. It has a built-in programmable execution engine that can be programmed to operate as almost any serial bus (I2C, SPI, EasyScale, and others). This patch adds a driver for this controller device. The driver does not expose a user-land interface. Protocol drivers built on top of this layer are expected to remain in-kernel.

2010-05-28mfd: AB3100 register access change to abx500 APIMattias Wallin
The interface for the AB3100 is changed to make way for the ABX500 family of chips: AB3550, AB5500 and future ST-Ericsson Analog Baseband chips. The register access functions are moved out to a separate struct abx500_ops. In this way the interface is moved from the implementation and the sub functionality drivers can keep their interface intact when chip infrastructure and communication mechanisms changes. We also define the AB3550 device IDs and the AB3550 platform data struct and convert the catenated 32bit event to an array of 3 x 8bits.

2010-03-07mfd: Use AB3100 MFD core IRQ for interrupt randomnessLinus Walleij
This reintroduces the entropy sampling of the AB3100 IRQ as the IRQF_SAMPLE_RANDOM is going out according to the feature removal schedule. I'm trying to do this the right way then, so CC:ing some random people for a quick review. We add entropy for interrupt events in the AB3100 which are truly random in nature, like external cables being connected, voltages on batteries dropping below certain ranges, ADC triggers or overheating.

2010-03-07mfd: Add HTCPLD driverCory Maccarrone
This change introduces a driver for the HTC PLD chip found on some smartphones, such as the HTC Wizard and HTC Herald. It works through the I2C bus and acts as a GPIO extender. Specifically: * it can have several sub-devices, each with its own I2C address * Each sub-device provides 8 output and 8 input pins * The chip attaches to one GPIO to signal when any of the input GPIOs change -- at which point all chips must be scanned for changes This driver implements the GPIOs throught the kernel's GPIO and IRQ framework. This allows any GPIO-servicing drivers to operate on htcpld pins, such as the gpio-keys and gpio-leds drivers.
