2013-07-01regulator: max8998: Use arrays for specifying voltages in platform dataTomasz Figa1-67/+29
This patch modifies the platform data of max8998 to use arrays for specifying predefined voltages of buck1 and buck2 instead of separate field for each voltage. This allows to simplify the code a bit and will help in adding support for Device Tree, which will be introduced in further patch.

2013-07-01mfd: max8998: Add irq domain supportTomasz Figa3-26/+52
This patch adds irq domain support for max8998 interrupts. To keep both non-DT and DT worlds happy, simple domain is used, which is linear when no explicit IRQ base is specified and legacy, with static mapping, otherwise.

2013-06-24mfd: palmas: Add TPS659038 PMIC supportJ Keerthy1-0/+5
The Patch adds TPS659038 PMIC support in the palmas mfd driver. The TPS659038 has almost the same registers as of the earlier supported variants of PALMAS family such as the TWL6035. The critical differences between TPS659038 and TWL6035 being: 1) TPS659038 has nothing related to battery charging and back up battery stuff. 2) TPS659038 does not have does not have SMPS10(Boost) step up convertor. 3) TPS659038 does not have Battery detection and anything related to battery. 4) SD card detection, Battery presence detection, Vibrator, USB OTG are missing when compared to TWL6035.

2013-06-20mfd: twl-core: Change TWL6025 references to TWL6032Graeme Gregory3-62/+62
The TWL6025 was never released beyond sample form and was replaced by the PhoenixLite range of chips - TWL6032. Change the references to reference the TWL6032 class and name the registers to twl6032 in line with an actual released chip name to avoid confusion. Currently there are no users of TWL6025 in the code.

2013-06-19mfd: vexpress: Make the driver optional for arm and arm64Pawel Moll2-3/+10
The driver can be used on either arm or arm64 platforms, but the latter doesn't have any platform-specific configuration options, so it must be possible to manually enable the driver. As the gpiolib is optional for arm64 arch, the gpio/led code must be compiled conditionally.

Also use dev_err() to keep consistency and drop the .remove function because the devm functions take care of what it's doing besides the now obsolete platform_set_drvdata() which we can just drop.

2013-06-18mfd: twl4030: Allow IRQ wake enable to succeed on subchip IRQsKevin Hilman1-0/+1
The genirq IRQ wake method will default to failure if the irq_chip does not provide a set_wake method. However, for TWL4030 sub-chip IRQs, we want the wake enable to succeed even though we don't provide a set_wake method. This allows sub-chip IRQs to still be flagged as wakeup capable, and allow them to wakeup from suspend (or abort suspend if they fire during suspend.) To fix, use the IRQCHIP_SKIP_SET_WAKE flag in the irq_chip. Signed-off-by: Kevin Hilman <khilman@linaro.org> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2013-06-13Merge tag 'am335x_tsc-adc' of git://breakpoint.cc/bigeasy/linuxSamuel Ortiz3-140/+392
A complete refurbished series inclunding: - DT support for the MFD, TSC and ADC driver & platform device support, which has no users, has been killed. - iio_map from last series is gone and replaced by proper nodes in the device tree. - suspend fixes which means correct data structs are taken and no interrupt storm - fifo split which should problem with TSC & ADC beeing used at the same time - The ADC channels are now checked before blindly applied. That means the touch part reads X, Y and Z coordinates and does not mix them up. Same goes for the IIO ADC driver. - The IIO ADC driver now creates files named in_voltageX_raw where X represents the ADC line instead of a number starting at 0. A read from this file can return -EBUSY in case touch is busy and the ADC didn't collect a value.
