* Revert "mfd: sec-core: Prepare regulators for suspend state to reduce ↵Javier Martinez Canillas2014-11-25
| | | | | | | | | | | | | | | | | | | | | | power-consumption" This reverts commit b7cde7078d2344073c310aa65fc2b0a845d2cb5b ("mfd: sec-core: Prepare regulators for suspend state to reduce power-consumption") Commit b7cde7078d23 called regulator_suspend_prepare() to prepare the regulators for a suspend state. But it did from the device pm suspend handler while the regulator suspend prepare function iterates over all regulators and not only the one managed by this device so it doesn't seems to be correct to call it from within a device driver. It is better to call the regulator suspend prepare/finish functions from platform code instead so this patch reverts the mentioned commit.

* mfd: sec-core: Fix IRQ handling after resume if this is not a wakeup sourceKrzysztof Kozlowski2014-06-03
| | | | | | | | | | | | | | During suspend the IRQ should be disabled even if this is not a wakeup source. This is a proper way of fixing the IRQ handling issue during resume (IRQ handler fails because I2C bus did not resume yet). When device is suspended and sec-core interrupt is signaled the irq chip will try to handle it regardless of wakeup source. Device could be woken up by different IRQ but still the IRQ handler will try to read the registers over I2C bus and fail because I2C bus won't be ready yet.

| | | | | | | | | | | | | | | | | | The rtc-s5m driver does not support all of S2M and S5M chipsets supported by main MFD sec-core driver. For such chipsets unsupported by rtc-s5m, the MFD sec-core driver initialized regmap with default config. This config in such cases wouldn't work at all. The main MFD sec-core driver shouldn't initialize regmap for child drivers which is not used by them and even not valid. Move the allocation of RTC I2C dummy device and initialization of RTC regmap from main MFD sec-core driver to the rtc-s5m driver.

When device is woken up from suspend by RTC Alarm, an interrupt occurs before resuming I2C bus controller. The interrupt is handled by regmap_irq_thread which tries to read RTC registers. This read fails (I2C is still suspended) and RTC Alarm interrupt is disabled. Disable the S5M8767 interrupts during suspend (disable_irq()) and enable them during resume so the device will be still woken up but the interrupt won't happen before resuming I2C bus.

* mfd: core: Push irqdomain mapping out into devicesMark Brown2012-09-15
| | | | | | | | | | | | | | | | | | | | | 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.
