2013-05-17mfd: ab8500-sysctrl: Always enable pm_power_off handlerFabio Baltieri
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.

git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next Pull MFD update from Samuel Ortiz: "For 3.10 we have a few new MFD drivers for: - The ChromeOS embedded controller which provides keyboard, battery and power management services. This controller is accessible through i2c or SPI. - Silicon Laboratories 476x controller, providing access to their FM chipset and their audio codec. - Realtek's RTS5249, a memory stick, MMC and SD/SDIO PCI based reader. - Nokia's Tahvo power button and watchdog device. This device is very similar to Retu and is thus supported by the same code base. - STMicroelectronics STMPE1801, a keyboard and GPIO controller supported by the stmpe driver. - ST-Ericsson AB8540 and AB8505 power management and voltage converter controllers through the existing ab8500 code. Some other drivers got cleaned up or improved. In particular: - The Linaro/STE guys got the ab8500 driver in sync with their internal code through a series of optimizations, fixes and improvements. - The AS3711 and OMAP USB drivers now have DT support. - The arizona clock and interrupt handling code got improved. - The wm5102 register patch and boot mechanism also got improved." * tag 'mfd-3.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next: (104 commits) mfd: si476x: Don't use 0bNNN mfd: vexpress: Handle pending config transactions mfd: ab8500: Export ab8500_gpadc_sw_hw_convert properly mfd: si476x: Fix i2c warning mfd: si476x: Add header files and Kbuild plumbing mfd: si476x: Add chip properties handling code mfd: si476x: Add the bulk of the core driver mfd: si476x: Add commands abstraction layer mfd: rtsx: Support RTS5249 mfd: retu: Add Tahvo support mfd: ucb1400: Pass ucb1400-gpio data through ac97 bus mfd: wm8994: Add some OF properties mfd: wm8994: Add device ID data to WM8994 OF device IDs input: Export matrix_keypad_parse_of_params() mfd: tps65090: Add compatible string for charger subnode mfd: db8500-prcmu: Support platform dependant device selection mfd: syscon: Fix warnings when printing resource_size_t of: Add stub of_get_parent for non-OF builds mfd: omap-usb-tll: Convert to devm_ioremap_resource() mfd: omap-usb-host: Convert to devm_ioremap_resource() ...

2013-04-18regulator: palmas: preserve modes of rails during enable/disableLaxman Dewangan
The Palma device like TPS65913 have the mode mask which is also used for enable/disable the rails. The mode bits are defined as 00: OFF 01: AUTO 10: ECO 11: Forced PWM and modes are set accordingly as REGULATOR_MODE_NORMAL: AUTO REGULATOR_MODE_IDLE: ECO REGULATOR_MODE_FAST: PWM Two issue observed: 1. If client calls following sequence: regulator_enable(), regulator_set_mode(FAST), regulator_disable() and again the regulator_enable() then the mode is reset to NORMAL inplace of keeping the mode as FAST. Fixing this by storing the current mode configured by client and restoring modes when enable() is called after disable(). 2. In following sequence, the regulator get enabled: regulator_disable() regulator_set_mode(FAST), Fixing this by updating new mode in register only if it is enabled.

2013-04-08ARM: ux500: move PM-related PRCMU functions to machineLinus Walleij
We are trying to decompose and decentralize the code in the DB8500 PRCMU out into subdrivers. The code moved in this patch concerns a group of functions used for decoupling and recoupling the IRQs from the GIC. During sleep and idle the Ux500 system will transfer all IRQ handling to the PRCMU using these functions. Basically we are left with the two alternatives of code placement as: - arch/arm/mach-ux500/pm.c - this because the code is closely related to the GIC, and takes ownership of some of the registers from the PRCMU related to this PM functionality. - drivers/mfd/db8500-prcmu-pm.c - because the code is affecting stuff in the PRCMU register range. But then this code needs to remap and handle GIC registers. This patch implementation is taking the first approach. Currently the cpuidle driver is the only piece of code using this set of functions, but it will later also be used by the suspend/resume code which is currently under review. The header file is moved to: <linux/platform_data/arm-ux500-pm.h> The function prototypes need to be placed in a globally visible header since the CPUidle code is planned to move out to drivers/cpuidle.

This patch will make an early remapping of the PRCMU, to be used when setting up the clocks, that will call down into parts of the PRCMU driver before it is probed. Going forward this will be removed like this: - The mailbox subsystem need to be merged. http://marc.info/?l=linux-kernel&m=136314559201983&w=2 - At this point the PRCMU clock code can be moved over to the ux500 clock driver in drivers/clk/ux500/* and maintained there in a decentralized manner. - This early initcall and PRCMU base parameters become part of the ux500_clk_init() call instead.

This patch allow using syscon driver from the platform data, i.e. possibility using driver on systems without oftree support. For search syscon device from the client drivers, "syscon_regmap_lookup_by_pdevname" function was added.

2013-04-05mfd: Add ChromeOS EC implementationSimon Glass
This is the base EC implementation, which provides a high level interface to the EC for use by the rest of the kernel. The actual communcations is dealt with by a separate protocol driver which registers itself with this interface. Interrupts are passed on through a notifier. A simple message structure is used to pass messages to the protocol driver.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/misc into char-misc-next Mark writes: extcon: arizona: Updates for v3.10 There's a bunch of different things in this series, I can split them out if need be: - Support for configuring the button detection circuit to reflect the accessories supplied with the system. - Improvements in the HPDET based detection scheme. - Additional robustness against more pathological use cases. - A few small standalone fixes.
2013-04-03ARM: ux500: Pass regulator platform data using the new formatLee Jones
Regulator platform data is now passed though a single structure as opposed to the old way where four separate struct elements were required. This patch makes use of the new format. Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2013-04-02extcon: arizona: Allow additional debounce during microphone detectionMark Brown
Help mitigate against mechanical bounce during the initial detection by allowing the configuration of an additional debounce on top of that the hardware does during the initial phase of microphone detection operation. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-04-02extcon: arizona: Simplify HPDET based identificationMark Brown
Rather than measuring both HP channels we can simply directly measure the microphone impedance and then rely on MICDET for final confirmation of the presence of a suitable microphone. This improves the overall performance of the identification process. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2013-04-02extcon: arizona: Allow configuration of button detectionMark Brown
The Arizona button detection circuit is configurable, allowing the system integrator to program a range of thresholds for the buttons supported on the accessory but currently the driver uses the default button ranges and does not provide any flexibility in how this is exposed to the application layer. Provide platform data allowing the user to control this and to map the buttons to keys in the input subsystem. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/misc into asoc-arizona ASoC/extcon: arizona: Fix interaction between HPDET and headphone outputs This patch series covers both ASoC and extcon subsystems and fixes an interaction between the HPDET function and the headphone outputs - we really shouldn't run HPDET while the headphone is active. The first patch is a refactoring to make the extcon side easier.
