2012-11-20mfd: sta2x11-mfd: Add apb-soc regs driver and factor out common codeDavide Ciminaghi
A driver for the apb-soc registers is needed by the clock infrastructure code to configure and control clocks on the sta2x11 chip. Since some of the functions in sta2x11-mfd.c were almost identical for the two existing platform devices, the following changes have been performed to avoid further code duplication while adding the apb-soc-regs driver: * The sctl_regs and apbreg_regs fields in struct sta2x11_mfd have been turned into just one array of pointers accessed by device index. * Platform probe methods have become one-liners invoking a common probe with the device's index as second parameter. * For loops have been inserted where the same operations were performed for each of the two bars of a pci device. * The apbreg_mask and sctl_mask functions were almost identical, so they were turned into inline functions invoking a common __sta2x11_mfd_mask() with the platform device's index as last parameter. To do this, enum sta2x11_mfd_plat_dev has been declared in sta2x11-mfd.h and more device types have been added to it.

2012-11-20mfd: Only unregister platform devices allocated by the mfd coreCharles Keepax
mfd_remove_devices would iterate over all devices sharing a parent with an mfd device regardless of whether they were allocated by the mfd core or not. This especially caused problems when the device structure was not contained within a platform_device, because to_platform_device is used on each device pointer. This patch defines a device_type for mfd devices and checks this is present from mfd_remove_devices_fn before processing the device.

2012-11-20mfd: da9052-core: Use regmap_irq_get_virq() and fix the probeFabio Estevam
On a mx53qsb dt-kernel the da9052-core driver fails to probe as follows: da9052 1-0048: DA9052 ADC IRQ failed ret=-22 The reason for the error was due to passing only the offset as the interrupt number in request_threaded_irq() without da9052->irq_base. The recommended approach though is to use regmap_get_virq() to acquire the interrupt number and this allows to get rid of da9052->irq_base. Fix it and allow the driver to probe successfully.

2012-11-11mfd: Prevent STMPE from abusing mfd_add_devices' irq_base parameterLee Jones
Originally IRQ incrementers were provided in some template resource structures for keypad and touchscreen devices. These were passed as IORESOURCE_IRQs to MFD core in the usual way. The true device IRQs were instead added to the irq_base when mfd_add_devices was invoked. This is clearly an abuse of the call, and does not scale when IRQ Domains are brought into play. Before we can provide the STMPE with its own IRQ Domain we must first fix this. This patche keeps most of the driver's structure, keeping the template strategy. However, instead of providing the IRQ as an increment to irq_base, we dynamically populate the IORESOURCE_IRQ with the correct device IRQ.
