* mfd: palmas: Add device tree handling to mfdGraeme Gregory2012-09-23
| | | | | | | | Add device tree handling to the palmas MFD. This takes the values that can be set from platform data from the device tree nodes instead. Signed-off-by: Graeme Gregory <gg@slimlogic.co.uk> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* mfd: palmas: Add pdata/data for rest of childrenGraeme Gregory2012-09-23
| | | | | | | | Add the platform data and data structures for children that shall be added by a future set of commits. Signed-off-by: Graeme Gregory <gg@slimlogic.co.uk> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* mfd: palmas: Switch to linear domain in all casesGraeme Gregory2012-09-21
| | | | | | | | | | | | Swith the palmas to linear domain in all cases so in future DT and non DT cases will work the same. With this patch children no longer need IRQ resources as it's easier for them to use regmap_get_virq. So we can remove the resources definitions.

* mfd: palmas: Improve the error exit pathGraeme Gregory2012-09-21
| | | | | | | | Improve the error exit path so that we correctly de-allocate resources that have been allocated upto the point where error occurs. Signed-off-by: Graeme Gregory <gg@slimlogic.co.uk> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* mfd: palmas: Drop kfree of devm_kzalloc's dataJulia Lawall2012-09-17
| | | | | | | | | | | | | | | | | | | | Using kfree to free data allocated with devm_kzalloc causes double frees. The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x; @@ x = devm_kzalloc(...) ... ?-kfree(x); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* mfd: core: Push irqdomain mapping out into devicesMark Brown2012-09-14
| | | | | | | | | | | | | | | | | | | | | Currently the MFD core supports remapping MFD cell interrupts using an irqdomain but only if the MFD is being instantiated using device tree and only if the device tree bindings use the pattern of registering IPs in the device tree with compatible properties. This will be actively harmful for drivers which support non-DT platforms and use this pattern for their DT bindings as it will mean that the core will silently change remapping behaviour and it is also limiting for drivers which don't do DT with this particular pattern. There is also a potential fragility if there are interrupts not associated with MFD cells and all the cells are omitted from the device tree for some reason. Instead change the code to take an IRQ domain as an optional argument, allowing drivers to take the decision about the parent domain for their interrupts. The one current user of this feature is ab8500-core, it has the domain lookup pushed out into the driver.

* mfd: Add missing hunk to change palmas irq to clear on readGraeme Gregory2012-07-08
| | | | | | | | | During conversion to regmap_irq this hunk was missing being moved to MFD driver to put the chip into clear on read mode. Also as slave is now set use it to determine which slave for the register call. Signed-off-by: Graeme Gregory <gg@slimlogic.co.uk> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* mfd: Fix palmas regulator pdata missingGraeme Gregory2012-07-08
| | | | | | | | | Due to a merge error the section of code passing the pdata for the regulator driver to the mfd_add_devices via the children structure was missing. This corrects this problem. Signed-off-by: Graeme Gregory <gg@slimlogic.co.uk> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

* mfd: palmas PMIC device supportGraeme Gregory2012-05-18
Palmas is a PMIC from Texas Instruments and this is the MFD part of the driver for this chip. The PMIC has SMPS and LDO regulators, a general purpose ADC, GPIO, USB OTG mode detection, watchdog and RTC features.
