* mfd: core: Push irqdomain mapping out into devicesMark Brown2012-09-151-1/+1
| | | | | | | | | | | | | | | | | | | | | Currently the MFD core supports remapping MFD cell interrupts using an irqdomain but only if the MFD is being instantiated using device tree and only if the device tree bindings use the pattern of registering IPs in the device tree with compatible properties. This will be actively harmful for drivers which support non-DT platforms and use this pattern for their DT bindings as it will mean that the core will silently change remapping behaviour and it is also limiting for drivers which don't do DT with this particular pattern. There is also a potential fragility if there are interrupts not associated with MFD cells and all the cells are omitted from the device tree for some reason. Instead change the code to take an IRQ domain as an optional argument, allowing drivers to take the decision about the parent domain for their interrupts. The one current user of this feature is ab8500-core, it has the domain lookup pushed out into the driver.

* mfd: Convert MFD drivers to use module_platform_driverMark Brown2012-01-091-11/+1
| | | | | | | | | Factors out some boilerplate code for drivers doing the default thing for platform driver registration. Drivers using platform_driver_probe or an initcall other than module_init can't be converted.

* mfd: add driver for sequencer serial portCyril Chemparathy2011-03-151-0/+476
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.
