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() ...
2013-05-01Merge tag 'for-v3.10' of git://git.infradead.org/battery-2.6Linus Torvalds37-659/+2521
Pull battery updates from Anton Vorontsov: "Highlights: - OpenFirmware/DeviceTree support for the Power Supply core: the core now automatically populates supplied_from hierarchy from the device tree. With these patches chargers and batteries can now lookup each other without the board files support shim. Rhyland Klein at NVIDIA did the work - New ST-Ericsson ABX500 hwmon driver. The driver is heavily using the AB85xx core and depends on some recent changes to it, so that is why the driver comes through the battery tree. It has an appropriate ack from the hwmon maintainer (i.e. Guenter Roeck). Martin Persson at ST-Ericsson and Hongbo Zhang at Linaro authored the driver - Final bits to sync AB85xx ST-Ericsson changes into mainline. The changes touch mfd parts, but these were acked by the appropriate MFD maintainer (ie Samuel Ortiz). Lee Jones at Linaro did most of the work and lead the submission process. Minor changes, but still worth mentioning: - Battery temperature reporting fix for Nokia N900 phones - Versatile Express poweroff driver moved into drivers/power/reset/ - Tree-wide: use devm_kzalloc() where appropriate - Tree-wide: dev_pm_ops cleanups/fixes" * tag 'for-v3.10' of git://git.infradead.org/battery-2.6: (112 commits) pm2301-charger: Fix suspend/resume charger-manager: Use kmemdup instead of kzalloc + memcpy power_supply: Populate supplied_from hierarchy from the device tree power_supply: Add core support for supplied_from power_supply: Define Binding for power-supplies rx51_battery: Fix reporting temperature hwmon: Add ST-Ericsson ABX500 hwmon driver ab8500_bmdata: Export abx500_res_to_temp tables for hwmon ab8500_{bmdata,fg}: Add const attributes to some data arrays ab8500_bmdata: Eliminate CamelCase warning of some variables ab8500_btemp: Make ab8500_btemp_get* interfaces public goldfish_battery: Use resource_size() lp8788-charger: Use PAGE_SIZE for the sysfs read operation max8925_power: Use devm_kzalloc() da9030_battery: Use devm_kzalloc() da9052-battery: Use devm_kzalloc() ds2760_battery: Use devm_kzalloc() ds2780_battery: Use devm_kzalloc() gpio-charger: Use devm_kzalloc() isp1704_charger: Use devm_kzalloc() ...

2013-04-17pm2301-charger: Fix suspend/resumeLars-Peter Clausen1-8/+18
The pm2301-charger driver implements runtime pm and at the same time uses the legacy pm callbacks for suspend and resume. This does not work since the I2C core wont look at the legacy pm callbacks if a driver has the 'pm' field set. This patch fixes it by moving over to dev_pm_ops for suspend/resume as well.

This patch adds support for the tps65090 charger driver. This driver is responsible for controlling the charger aspect of the tps65090 mfd. Currently, this mainly consists of turning on and off the charger, but some features of the charger can be supported through this driver including: - Enable Auto Recharge based on Battery voltage - Fast Charge Safety Timer - Maximum battery discharge current - Maximum battery adapter current - Enable External Charge - Disable charging termination based on low charger current (supported) Once the driver is accepted, later patches can add support for the features above which are not yet supported.
