2012-05-20mfd: Fix return type of lm533 attribute is_visibleJohan Hovold1-1/+1
Since commit 587a1f1659 ("switch ->is_visible() to returning umode_t") the return type of is_visible is umode_t rather than mode_t. This silences a compiler warning on some architectures where these types are not compatible.

2012-05-20mfd: Add support for Device Tree to twl6040Peter Ujfalusi3-8/+87
Device tree based probing support for the core twl6040 driver. Child devices will be created as MFD devices: - ASoC codec is always created - Vibra child is only created if the vibra section present in the DT blob.

2012-05-20mfd: Register the twl6040 child for the ASoC codec unconditionallyPeter Ujfalusi1-20/+19
The main function of the twl6040 is to provide audio on OMAP4+ platforms. Since the ASoC codec driver can work without the pdata we can register the child to load the codec driver whenever the twl6040 MFD driver is loaded.

2012-05-20mfd: Allocate twl6040 IRQ numbers dynamicallyPeter Ujfalusi2-4/+12
Use irq_alloc_descs() to get the IRQ number range dynamically instead of the hardwired use if pdata->irq_base. The twl6040 only provides interrupts for it's internal components which means that it is not working as an IRQ expander type of device. The client drivers will receive their interrupt numbers as resource which is configured based on the received IRQ range we got from irq_alloc_descs() Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

Before this patch if probe failed to find the platform IRQ it would attempt to print a message out using dev_err, which in turn was being passed an unassigned pointer.

2012-05-20mfd: Enable Device Tree for ab8500-core driverLee Jones1-21/+50
This patch will allow the ab8500-core driver to be probed and set up when booting when Device Tree is enabled. This includes platform ID look-up which identifies the machine it is currently running on. If we are undergoing a DT enabled boot, we will refuse to setup each of the other ab8500-* devices, as they will be probed individually by DT.

2012-05-20mfd: Remove confusing ab8500-i2c file and merge into ab8500-coreLee Jones4-169/+103
ab8500-i2c is used as core code to register the ab8500 device. After allocating ab8500 memory, it immediately calls into ab8500-core where the real initialisation takes place. This patch moves all core registration and memory allocation into the true ab8500-core file and removes ab8500-i2c completely.

2012-05-20mfd: Convert wm831x to irq_domainMark Brown13-84/+131
The modern idiom is to use irq_domain to allocate interrupts. This is useful partly to allow further infrastructure to be based on the domains and partly because it makes it much easier to allocate virtual interrupts to devices as we don't need to allocate a contiguous range of interrupt numbers. Convert the wm831x driver over to this infrastructure, using a legacy IRQ mapping if an irq_base is specified in platform data and otherwise using a linear mapping, always registering the interrupts even if they won't ever be used. Only boards which need to use the GPIOs as interrupts should need to use an irq_base. This means that we can't use the MFD irq_base management since the unless we're using an explicit irq_base from platform data we can't rely on a linear mapping of interrupts. Instead we need to map things via the irq_domain - provide a conveniencem function wm831x_irq() to save a small amount of typing when doing so. Looking at this I couldn't clearly see anything the MFD core could do to make this nicer. Since we're not supporting device tree yet there's no meaningful advantage if we don't do this conversion in one, the fact that the interrupt resources are used for repeated IP blocks makes accessor functions for the irq_domain more trouble to do than they're worth.
