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. Also provide a few more error logs and change the irq string to "adc-irq", so that it appears as a single word in 'cat /proc/interrupts' Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Reviwed-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

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.

These IRQ ranges, like any other MFD related IRQ resource are passed though MFD core for automatic conversion to virtual IRQs; however, MFD core does not support IRQ mapping of IRQ ranges. Let's just remove them.

If the same step is applied several times, the coordinate values read are more accurate. Hence we provide the user an option of how many steps should be configured. For ex: If this value is assigned as 4, This means that 4 steps are applied to read x co-ordinate and 4 steps to read y co-ordinate. Furtheron the interrupt handler already holds code to use delta filter and report the best value out of these values to the input sub-system.
