2009-06-17mfd: add PCAP driverDaniel Ribeiro
The PCAP Asic as present on EZX phones is a multi function device with voltage regulators, ADC, touch screen controller, RTC, USB transceiver, leds controller, and audio codec. It has two SPI ports, typically one is connected to the application processor and another to the baseband, this driver provides read/write functions to its registers, irq demultiplexer and ADC queueing/abstraction. This chip is used on a lot of Motorola phones, it was manufactured by TI as a custom product with the name PTWL93017, later this design evolved into the ATLAS PMIC from Freescale (MC13783).

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.

2009-06-17drivers/mfd: remove obsolete irq_desc_t typedefThomas Gleixner
The defines and typedefs (hw_interrupt_type, no_irq_type, irq_desc_t) have been kept around for migration reasons. After more than two years it's time to remove them finally. This patch cleans up one of the remaining users. When all such patches hit mainline we can remove the defines and typedefs finally. Impact: cleanup Convert the last remaining users and remove the typedef.

2009-06-17mfd: Mark clocks_init as non-init in twl4030-core.cRakib Mullick
Impact: Fix section mismatch. clocks_init() has been called from twl4030_probe() which is a non-init function. Since probing can be done anytime so clocks_init will be called anytime too. So we mark clock_init() as non-init. LD drivers/mfd/built-in.o WARNING: drivers/mfd/built-in.o(.text+0x8dd9): Section mismatch in reference from the function twl4030_probe() to the function .init.text:clocks_init() The function twl4030_probe() references the function __init clocks_init().

2009-06-15mfd: remove driver_data direct access of struct deviceGreg Kroah-Hartman
In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions.

2009-05-19mfd: Keep a cache of WM8350 volatile valuesMark Brown
Due to the way that the WM8350 audio driver handles CODEC_ENA many of the WM8350 audio registers are marked as volatile when they aren't actually so. Allow the audio driver to see a cache of these values for inspection during interrupt context. To do this we need to stop satisfying any bits from volatile registers from cache - there's no real benefit from doing so anyway, we did the read already.

2009-04-05mfd: Use bulk read to fill WM8350 register cacheMark Brown
Some I2C controllers have high overheads for setting up I2C operations which makes the register cache setup on startup excessively slow since it does a lot of small transactions.

2009-01-08leds: Add WM8350 LED driverMark Brown
The voltage and current regulators on the WM8350 AudioPlus PMIC can be used in concert to provide a power efficient LED driver. This driver implements support for this within the standard LED class. Platform initialisation code should configure the LED hardware in the init callback provided by the WM8350 core driver. The callback should use wm8350_isink_set_flash(), wm8350_dcdc25_set_mode() and wm8350_dcdc_set_slot() to configure the operating parameters of the regulators for their hardware and then then use wm8350_register_led() to instantiate the LED driver.
