* mfd: core: Push irqdomain mapping out into devicesMark Brown2012-09-151-3/+3
| | | | | | | | | | | | | | | | | | | | | 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: Initial support for the WM5110Mark Brown2012-07-161-0/+24
| | | | | | | | | | | The WM5110 is a highly-integrated low-power audio system for smartphones, tablets and other portable audio devices. It combines an advanced DSP feature set with a flexible, high-performance audio hub CODEC. The support is based on the Arizona core driver.

* mfd: Move arizona digital core supply management to the regulator APIMark Brown2012-07-091-30/+35
| | | | | | | | | | Rather than open coding the enable GPIO control in the MFD core use the API to push the management on to the regulator driver. The immediate advantage is slight for most systems but this will in future allow device configurations where an external regulator is used for DCVDD.

* mfd: arizona: Core driverMark Brown2012-06-231-0/+527
Several forthcoming Wolfson devices are based on a common platform known as Arizona allowing a great deal of reuse of driver code. This patch adds core support for these devices. In order to handle systems which do not use the generic clock API a simple wrapper for the 32kHz clock domain in the devices is provided. Once the generic clock API is widely available this code will be moved over to use that. For simplicity some WM5102 specific code is included in the core driver, the effort involved in splitting the device out isn't worth it.
