2011-10-24mfd: Move to the new db500 PRCMU APIMattias Nilsson3-304/+174
Now that we have a shared API between the DB8500 and DB5500 PRCMU's, switch to using this neutral API instead. We delete the parts of db8500-prcmu.h that is now PRCMU-neutral, and calls will be diverted to respective driver. Common registers are in dbx500-prcmu-regs.h and common accessors and defines in <linux/mfd/dbx500-prcmu.h> This way we get a a lot more abstraction and code reuse.

2011-10-24mfd: Delete ab3550 driverLinus Walleij1-47/+1
The AB3550 never passed the prototype stage. Instead it was used as a precursor to AB5500 for testing basic building blocks used in that chip, since they had large similarities. Since AB3550 will not see the light of day in product form and since the prototypes are no longer used, let's delete the driver and any references to it.

2011-10-24mfd: ab5500 chip register accessMattias Wallin2-2/+142
The analog baseband chip ab5500 is a multi functional chip containing regulators, charging, gpio, USB and accessory detect. It also contain various multimedia functionalities like digital encoder and audio codec. The core driver added with this patch provides register access via i2c via PRCMU. Event handling implemented as irq_chip will come in future patches since it depends on PRCMU functionality not yet implemented.

2011-10-24mfd: Add Intel MSIC driverMika Westerberg1-0/+456
Add support for Intel MSIC chip found on Intel Medfield platforms. This chip embeds several subdevices: audio, ADC, GPIO, power button, etc. The driver creates platform device for each subdevice. We also provide an MSIC register access API which should replace the more generic SCU IPC interface currently used. Existing drivers can choose whether they convert to this new API or stick with the SCU IPC interface.

2011-10-24mfd: Simulate active high IRQs with wm831xMark Brown1-0/+1
In order to ease system integration provide a simulation of active high IRQs on the GPIOs by polling the GPIO status when an IRQ is generated. This isn't ideal on several fronts and will miss initially active IRQs in the current implementation but it should work well for most cases.

In systems where there is no hardware signal from the processor to the PMIC to initiate the final power off sequence we must initiate the shutdown with a register write to the PMIC.

2011-07-31mfd: Support multiple active WM831x AUXADC conversionsMark Brown1-2/+11
The WM831x AUXADC hardware can schedule multiple conversions at once, allowing higher performance when more than one source is in use as we can have the hardware start new conversions without having to wait for a register write. Take advantage of this in the interrupt driven case, maintaining a list of callers that are waiting for AUXADC conversions and completing them all simultaneously. The external interface of the AUXADC is not changed so there will be limited use of the feature immediately.
