* mfd: Convert AB3500 to new irq_ APIsMark Brown2011-01-141-15/+13
| | | | | | | | | | | The genirq core is being updated to pass struct irq_data rather than irq numbers into chip drivers. As part of the update assignments to NULL for unused operations are removed, these are not needed and the genirq docs should be good enough.

| | | | | | | | | | | | | | | ... and convert it to a dev_info print at probe time. There are many variants of this chip with different values of VERSIONCRC. The set of values is large, and not useful to enumerate. All are SW compatible. The difference lies in default settings of the various power rails, and other similar differences. The driver, or clients of the driver, shouldn't be affected by this, since all rails should be programmed into the desired state in all cases for correct operation.

* mfd: Implement runtime PM for WM8994 core driverMark Brown2011-01-141-23/+23
| | | | | | | | | | | | Allow the WM8994 to completely power off, including disabling the LDOs if they are software controlled, when it goes idle. The CODEC subdevice controls activity for the MFD as a whole. If the GPIOs need to be used while the device is active runtime PM should be disabled for the device by machine specific code.

| | | | | | | | | | | | Allow MFD cells to have pm_runtime_no_callbacks() called on them during registration. This causes the runtime PM framework to ignore them, allowing use of runtime PM to suspend the device as a whole even if not all drivers for the MFD can usefully implement runtime PM. For example, RTCs are likely to run continuously regardless of the power state of the system.

Some ACPI drivers, e.g. button, have their procfs I/F always built in, because we don't have sysfs I/F replacement at the moment. But once we finish developing the sysfs I/F for these driver, we need CONFIG_ACPI_PROCFS to enabled/disable the corresponding procfs I/F. So just updating the description rather than removing this option, although there is no procfs I/F depends on it for now.
