drivers/mfd/ab3100-core.c:647: error: ab3100_init_settings causes a section type conflict Cc: Anton Vorontsov <avorontsov@ru.mvista.com> Cc: Samuel Ortiz <sameo@linux.intel.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: <stable@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-09-17regulator: AB3100 supportLinus Walleij
This adds support for the regulators found in the AB3100 Mixed-Signal IC. It further also defines platform data for the ST-Ericsson U300 platform and extends the AB3100 MFD driver so that platform/board data with regulation constraints and an init function can be passed down all the way from the board to the regulators.

2009-09-17mfd: Fix ab3100-otp build failureSamuel Ortiz
ab3100.h should include linux/workqueue.h for otp to build properly. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2009-09-17mfd: AB3100 disable irq nosyncLinus Walleij
This will make the worker fire interrupt disable the AB3100 IRQ without sync which resolves a race since the interrupt obviously cannot wait for itself to complete while being handled. Signed-off-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2009-09-17mfd: AB3100 alter default settingLinus Walleij
This alters the default setting for AB3100_IMRB1 from 0xff to 0xbf. These registers are used for the yet unimplemented ADC and this new setting will deactivate ADC Trigger 1. Signed-off-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2009-09-17mfd: AB3100 propagate errorLinus Walleij
This makes ab3100_set_register_interruptible() propagate the error code from suboperations properly so it can be handles properly. (A special case comes from signal interruption.) Signed-off-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2009-09-17mfd: AB3100 accessor function cleanupsLinus Walleij
This adds the _interruptible suffix to the AB3100 accessor functions on par with mutex_lock_interruptible() that's used for blocking simultaneous calls to the AB3100 acessor functions. Since these accesses are slow on a 100kHz I2C bus and may line up waiting for the mutex, we need to handle interruption by system shutdown or kill signals and may just as well denote that in the function names.

2009-09-17mfd: fix ab3100 warning on x86_64Samuel Ortiz
The file_operations write prototype should return a ssize_t. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2009-06-17mfd: add U300 AB3100 core supportLinus Walleij
This adds a core driver for the AB3100 mixed-signal circuit found in the ST-Ericsson U300 series platforms. This driver is a singleton proxy for all accesses to the AB3100 sub-drivers which will be merged on top of this one, RTC, regulators, battery and system power control, vibrator, LEDs, and an ALSA codec.
