* mfd: Support multiple active WM831x AUXADC conversionsMark Brown2011-07-311-77/+177
| | | | | | | | | | | | | | | 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.

* mfd: Allocate wm835x irq descs dynamicallySascha Hauer2011-07-311-6/+12
| | | | | | | | | | | | | This allows boards to leave the irq_base field unitialized and prevents them having to reserve irqs in the platform. pdata can be optional for irq support now. Without pdata the driver allocates some free irq range. With pdata and irq_base > 0 the driver allocates exactly the specified irq. Without pdata the irq defaults to IRQF_TRIGGER_LOW.

* mfd: Refactor wm831x AUXADC handling into a separate fileMark Brown2011-07-313-166/+201
| | | | | | | | | In preparation for some additional work on the wm831x AUXADC code move the support into a separate file. This is a simple code motion patch, there should be no functional changes.

* mfd: Read wm831x AUXADC conversion results before acknowledging interruptMark Brown2011-07-311-16/+31
| | | | | | | | | | Ensure that there's no possibility of loosing an AUXADC interrupt by reading the conversion result in the IRQ handler when using interrupts. Otherwise it's possible that under very heavy load a new conversion could be initiated before the acknowledgement for a previous interrupt has happened.

* mfd: Support dynamic allocation of IRQ range for wm831xMark Brown2011-07-311-5/+13

| | | | | | | | | | | | The WM831x IRQ set_type() operation is doing a direct register write when called but since set_type() is called with the bus lock held this isn't legal and could cause deadlocks in the IRQ core. Fix this by posting the updates into an array and syncing in the bus_sync_unlock() callback.

To support providing those values as lowest/highest attributes to the user, introduce virtual PMBus commands. Those commands reside outside the normal command set and have to be implemented in device specific code, which map the virtual commands to device specific commands.

An easy way to support such sensors is to introduce virtual pages and map the non-standard registers into standard registers on an extra page. For this to work, the code verifying if the configured number of pages exists has to be removed. Since a wrong number of pages can only be configured in a front-end driver, this should not have a practical impact since the resulting errors should be found during development and testing. Also, functions to read the chip status while checking if a command register exists must be modified to no longer set the page register before reading the status, since the physical page associated with the checked register may not exist. This does not make a functional difference since the page was already set when the attempt to read the register was made.

To support such devices, add code to support reading and writing of word size registers in device specific code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some hwmon sysfs attributes have a length of 20 bytes (plus terminating 0). I2C_NAME_SIZE is defined as 20 and thus can not be used to define the length of hwmon sysfs attributes. Replace it with PMBUS_NAME_SIZE, set to 24.

| * | | | hwmon: (pmbus) Add support for VID output voltage modeGuenter Roeck2011-07-297-34/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In VID mode, output voltages are measured and reported as VID values, and have to be converted to voltages using VID conversion tables or functions. Support is added for VR11 only at this time. This patch enables support for PMBus devices supporting VID VR11 based output voltage selection such as NCP4200 and NCP4208.
