2014-06-03mfd: arizona: Add MICVDD to mapped regulatorsCharles Keepax
Currently, MICVDD only binds because it is both the regulator name and the consumer name and we will always match against the regulator name regardless of the consumer device. If the regulator was renamed using the init_data ASoC will no longer be able to locate the supply, as it will be looking on the CODEC device where as the MICVDD consumer is on the Arizona device. Add a mapping as we do for the other regulators. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

2014-06-03mfd: Add driver for Atmel Microcontroller on iPaq h3xxxLinus Walleij
This adds a driver for the Atmel Microcontroller found on the iPAQ h3xxx series. This device handles some keys, the touchscreen, and the battery monitoring. This is a port of a driver from handhelds.org 2.6.21 kernel, written by Alessandro Gardich based on Andrew Christians original HAL-driver. It has been heavily cleaned and converted to mfd-core by Dmitry Artamonow and rewritten again for the v3.x series kernels by Linus Walleij, bringing back some of the functionality lost from Andrew's original driver.

2014-06-03mfd: syscon: Allow property as NULL in syscon_regmap_lookup_by_phandlePankaj Dubey
If we pass syscon device node itself as first parameter to this function there is no need to parse and find syscon device node. So by allowing "property" parameter as NULL allow syscon_regmap_lookup_by_phandle to consider passed argument "np" itself as a syscon device node "syscon_np". This will help us in avoiding addition of "syscon" property in a device node which points back to same device node in device tree.

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 max14577 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: max14577 2-0025: Failed to read IRQ status: -5 Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

2014-06-03mfd: sec-core: Remove duplicated device type from sec_pmic_devKrzysztof Kozlowski
The device type was stored in sec_pmic_dev state container twice: - unsigned long type (initialized from of_device_id or i2c_device_id) - int device_type (initialized as above or from board files when there is no DTS) The 'type' field was never used outside of probe so it can be safely removed.

2014-06-03mfd: twl6040: Clear the interrupt ID register before requesting IRQPeter Ujfalusi
If for some reason the boot loader enabled the audpwron GPIO we will have pending IRQs to be handled. This seams to break twl6040 for some reason leading to non working i2c communication (i2c timeouts). Clearing the INTID register after we requested the audpwron GPIO (and set it to low) will ensure that the chip will operate normally in this case as well.

2014-06-03mfd/rtc: s5m: Do not allocate RTC I2C dummy and regmap for unsupported chipsetsKrzysztof Kozlowski
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. The rtc-s5m driver will use proper regmap config for supported devices.
