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() ...

2012-11-05mfd: Versatile Express config infrastructurePawel Moll
Versatile Express platform has an elaborated configuration system, consisting of microcontrollers residing on the mother- and daughterboards known as Motherboard/Daughterboard Configuration Controller (MCC and DCC). The controllers are responsible for the platform initialization (reset generation, flash programming, FPGA bitfiles loading etc.) but also control clock generators, voltage regulators, gather environmental data like temperature, power consumption etc. Even the video output switch (FPGA) is controlled that way. Those devices are _not_ visible in the main address space and the usual communication channel uses some kind of a bridge in the peripheral block sending commands (requests) to the controllers and receiving responses. It can take up to 500 microseconds for a transaction to be completed, therefore it is important to provide a non-blocking interface to it. This patch adds an abstraction of this infrastructure. Bridge drivers can register themselves with the framework. Then, a driver of a device can request an abstract "function" - the request will be redirected to a bridge referred by thedd "arm,vexpress,config-bridge" property of the device tree node.

2012-10-05Merge tag 'mfd-3.7-1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6 Pull MFD changes from Samuel Ortiz: "MFD bits for the 3.7 merge window. As usual we have a few new drivers: - TI LP8788 - TI OMAP USB TLL - Maxim MAX8907 - SMSC ECE1099 - Dialog Semiconductor DA9055 - A simpler syscon driver that allow us to get rid of the anatop one. Drivers are also gradually getting Device Tree and IRQ domain support. The following drivers got DT support: - palmas, 88pm860x, tc3589x and twl4030-audio And those ones now use the IRQ domain APIs: - 88pm860x, tc3589x, db8500_prcmu Also some other interesting changes: - Intel's ICH LPC now supports Lynx Point - TI's twl4030-audio added a GPO child - tps6527 enabled its backlight subdevice - The twl6030 pwm driver moved to the new PWM subsystem And finally a bunch of cleanup and casual fixes for mc13xxx, 88pm860x, palmas, ab8500, wm8994, wm5110, max8907 and the tps65xxx family." Fix up various annoying conflicts: the DT and IRQ domain support came in twice and was already in 3.6. And then it was apparently rebased.

TI LP8788 PMU provides regulators, battery charger, ADC, RTC, backlight driver and current sinks. This MFD patch supports the I2C communication using the regmap, the interrupt handling using the linear IRQ domain and configurable platform data structures for each driver module. (Driver Architecture) < mfd devices > LP8788 HW .......... mfd .......... regulator drivers I2C power supply driver IRQs iio adc driver rtc driver backlight driver current sink drivers o regulators : LDOs and BUCKs o power supply : Battery charger o iio adc : Battery voltage/temperature o rtc : RTC and alarm o backlight o current sink : LED and vibrator All MFD device modules are registered by LP8788 MFD core driver. For sharing information such like the virtual IRQ number, MFD core driver uses the resource structure. Then each module can retrieve the specific IRQ number and detect it in the IRQ thread.
