2013-07-31mfd: Use dev_get_platdata()Jingoo Han
Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2013-06-11mfd: intel_msic: Remove unnecessary platform_set_drvdata()Jingoo Han
The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is not needed to manually clear the device driver data to NULL.

2013-05-18drivers/mfd: don't check resource with devm_ioremap_resourceWolfram Sang
devm_ioremap_resource does sanity checks on the given resource. No need to duplicate this in the driver. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2013-04-08mfd: intel_msic: Use devm_gpio_request_one()Jingoo Han
Use devm_gpio_request_one() to make cleanup paths more simple. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-01-25mfd: Convert to devm_ioremap_resource()Thierry Reding
Convert all uses of devm_request_and_ioremap() to the newly introduced devm_ioremap_resource() which provides more consistent error handling. devm_ioremap_resource() provides its own error messages so all explicit error messages can be removed from the failure code paths.

2012-09-15mfd: core: Push irqdomain mapping out into devicesMark Brown
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.

2012-05-01mfd: Convert Intel MSIC driver to use devm_* interfaces.Pasi Savanainen
The devm_* functions eliminate the need for manual resource releasing and simplify error handling. Resources allocated by devm_* are freed automatically on driver detach.

2012-01-09mfd: Convert MFD drivers to use module_platform_driverMark Brown
Factors out some boilerplate code for drivers doing the default thing for platform driver registration. Drivers using platform_driver_probe or an initcall other than module_init can't be converted.

2011-10-24mfd: Add Intel MSIC driverMika Westerberg
Add support for Intel MSIC chip found on Intel Medfield platforms. This chip embeds several subdevices: audio, ADC, GPIO, power button, etc. The driver creates platform device for each subdevice. We also provide an MSIC register access API which should replace the more generic SCU IPC interface currently used. Existing drivers can choose whether they convert to this new API or stick with the SCU IPC interface.
