2014-01-21mfd: sec: Add PM ops and make it a wake up sourceKrzysztof Kozlowski1-0/+40
Add PM suspend/resume ops to the sec MFD core driver and make it a wake up source. This allows proper waking from suspend to RAM and also fixes broken interrupts after resuming: [ 42.705703] sec_pmic 7-0066: Failed to read IRQ status: -5 Interrupts stop working after first resume initiated by them (e.g. by RTC Alarm interrupt) because interrupt registers were not cleared properly. 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.

As of commit 03e361b25ee8dfb1fd9b890072c23c4aae01c6c7 ("mfd: Stop setting refcounting pointers in original mfd_cell arrays"), the "cell" parameter of mfd_add_devices() is "const" again.

2013-12-18mfd: sec: Remove sec_reg* regmap helpersKrzysztof Kozlowski1-30/+0
Remove sec_reg* helpers as they are not used anymore. These helpers were error-prone as they mixed u8 with unsigned int and they changed order of some of parameters (val and mask in sec_reg_update()). Also the helpers didn't give any way of useful abstraction as they just called corresponding regmap function.

2013-12-12mfd/rtc: s5m: fix register updating by adding regmap for RTCKrzysztof Kozlowski1-8/+22
Rename old regmap field of "struct sec_pmic_dev" to "regmap_pmic" and add new regmap for RTC. On S5M8767A registers were not properly updated and read due to usage of the same regmap as the PMIC. This could be observed in various hangs, e.g. in infinite loop during waiting for UDR field change. On this chip family the RTC has different I2C address than PMIC so additional regmap is needed.

2013-07-31mfd: sec: Add register cache for interrupt mask registersMark Brown1-0/+31
The performance of regmap-irq is improved if the interrupt mask registers can be cached since it does read/modify/update cycles so start using the register cache infrastructure for those registers. We should use this more widely but I don't have a datasheet and this is a nice, conservative starting point.

2012-09-15mfd: core: Push irqdomain mapping out into devicesMark Brown1-4/+4
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.
