* mfd: intel: Constify struct mfd_cell where possibleGeert Uytterhoeven2014-01-061-1/+1
| | | | | | | | | | As of commit 03e361b25ee8dfb1fd9b890072c23c4aae01c6c7 ("mfd: Stop setting refcounting pointers in original mfd_cell arrays"), the "cell" parameter of mfd_add_devices() is "const" again. Hence make all cell data passed to mfd_add_devices() const where possible. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
* mfd: Use dev_get_platdata()Jingoo Han2013-07-311-2/+2

* mfd: intel_msic: Remove unnecessary platform_set_drvdata()Jingoo Han2013-06-111-1/+0
| | | | | | | | | | | | 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.

* drivers/mfd: don't check resource with devm_ioremap_resourceWolfram Sang2013-05-181-5/+0

* mfd: Convert to devm_ioremap_resource()Thierry Reding2013-01-251-5/+4
| | | | | | | | | | | | 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.

* mfd: core: Push irqdomain mapping out into devicesMark Brown2012-09-151-2/+2
| | | | | | | | | | | | | | | | | | | | | 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 Intel MSIC driverMika Westerberg2011-10-241-0/+501
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.
