* mfd: twl4030-audio: Remove unnecessary platform_set_drvdata()Jingoo Han2013-06-111-4/+1
| | | | | | | | | | | 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.

* mfd: Move ssbi driver into drivers/mfdArnd Bergmann2013-06-113-2/+382
| | | | | | | | | | | | | | | There is no reason for ssbi to have its own top-level driver directory when the only users of this interface are all MFD drivers. The only mainline driver using it at the moment (PM8921) is marked broken and in fact does not compile. I have verified that fixing the trivial build breakage in pm8921 links in the new ssbi code just fine, but that can be a separate patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously the DSI PLL divider rate was initialised statically and assumed to be 1. Before the common clock framework was enabled for ux500, a call to clk_set_rate() would always update the HW registers no matter what the current setting was. This patch makes sure the actual hw settings and the sw assumed settings are matched.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AB8500 sysctrl driver implements a pm_power_off handler, but that is currently not registered until a specific platform data field is enabled. This patch drops the platform data field and always registers ab8500_power_off if no other pm_power_off handler was defined before, and also introduces the necessary cleanup code in the driver's remove function.

| | | | | | | | | | | | | | | | | | | | | | | | When booting with Device Tree enabled the MFD core uses each device's compatible string to find and allocate its associated of_node pointer, which in turn is passed to the driver via the platform_device struct. Without it, the driver won't be able to interrogate the Device Tree or locate suitable regulators and will most likely fail to probe.

| | | | | | | | | | | | | | | | | | | | | | The MFD subsystem requires drivers to state the size of any platform data passed, or it will fail to assign it to the device.

| * mfd: ab8500-core: Use the correct driver name when enabling gpio/pinctrlLee Jones2013-05-171-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we're using Device Tree to enable GPIO drivers we're forced to be OS agnostic, thus we are forbidden use names like pinctrl as they are specific only to Linux, at least for the time being. However, when we are registering devices using internal systems such as MFD or platform registration, we can use such terminology. In this case we can and should use the platform device ID mechanism to specify which device we wish to utilise by detailing pinctrl-<device_name>. This patch fixes a regression that when booting with Device Tree enabled the ABx500 GPIO/Pinctrl devices are not probed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AB8500 debug code which was merged in parallell with the multiplatform work incidentally introduced a new instance using the <mach/irqs.h> header which is now deleted, causing this build regression: drivers/mfd/ab8500-debugfs.c:95:23: fatal error: mach/irqs.h: No such file or directory compilation terminated. make[4]: *** [drivers/mfd/ab8500-debugfs.o] Error 1 The code most certainly never worked with device tree either since that does not rely on this kind of hard-coded interrupt numbers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds all necessary header files and Kbuild plumbing for the core driver for Silicon Laboratories Si476x series of AM/FM tuner chips. The driver as a whole is implemented as an MFD device and this patch adds a core portion of it that provides all the necessary functionality to the two other drivers that represent radio and audio codec subsystems of the chip.

| | | | | | | | | | | | | | | | | | | | | | | | RTS5249 supports SD UHS-II interface. In order to support SD UHS-II，the definitions of some internal registers of RTS5249 have to be modified and are different from its predecessors. So we need this patch to ensure RTS5249 can work, even SD/MMC stack doesn't support UHS-II interface.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The main aim for this cycle is to have the u8540 booting to a console. However, the u8540 doesn't support all of the u8500 platform devices yet. After this stage is complete we can then fill in the inadequacies, such as specific clock support at a later date. To achieve this we're placing devices supported by all platforms into a common device structure and the remaining ones into a platform specific one.
