* mfd: PCF50633 gpio supportBalaji Rao2009-01-111-1/+2
| | | | | | | | | | What the PCF05633 calls as a 'GPIO' is much more than the GPIO in the linux sense and there are only 4 of them - which means, the gpiolib is not used here.

* mfd: PCF50633 adc driverBalaji Rao2009-01-111-1/+2
| | | | | | | | | | | | This patch adds basic support for the PCF50633 ADC. The subtractive mode is not supported yet. Since we don't have adc subsystem, it currently lives in drivers/mfd.

| | | | | | | | | | | | ove the menelaus driver from drivers/i2c/chips to drivers/mfd since it's more of a multi-function device than anything else, and since Jean is trying to vanish drivers/i2c/chips ASAP. One way to think of these chips are as the PMIC family most used with OMAP2 generation chips.

* mfd: dm355evm msp430 driverDavid Brownell2009-01-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basic MFD framework for the MSP430 microcontroller firmware used on the dm355evm board: - Provides an interface for other drivers: register read/write utilities, and register declarations. - Directly exports: * Many signals through the GPIO framework + LEDs + SW6 through gpio sysfs + NTSC/nPAL jumper through gpio sysfs + ... more could be added later, e.g. MMC signals * Child devices: + LEDs, via leds-gpio child (and default triggers) + RTC, via rtc-dm355evm child device + Buttons and IR control, via dm355evm_keys - Supports power-off system call. Use the reset button to power the board back up; the power supply LED will be on, but the MSP430 waits to re-activate the regulators. - On probe() this: * Announces firmware revision * Turns off the banked LEDs * Exports the resources noted above * Hooks the power-off support * Muxes tvp5146 -or- imager for video input Unless the new tvp514x driver (tracked for mainline) is configured, this assumes that some custom imager driver handles video-in. This completely ignores the registers reporting the output voltages on the various power supplies. Someone could add a hwmon interface if that seems useful.

* mfd: twl4030 IRQ handling updateDavid Brownell2008-10-221-1/+1
| | | | | | | | | | | | | | | | | | | | | - Move it into a separate file; clean and streamline it - Restructure the init code for reuse during secondary dispatch - Support both levels (primary, secondary) of IRQ dispatch - Use a workqueue for irq mask/unmask and trigger configuration Code for two subchips currently share that secondary handler code. One is the power subchip; its IRQs are now handled by this core, courtesy of this patch. The other is the GPIO module, which will be supported through a later patch. There are also minor changes to the header file, mostly related to GPIO support; nothing yet in mainline cares about those. A few references to OMAP-specific symbols are disabled; when they can all be removed, the TWL4030 support ceases being OMAP-specific.

* mfd: TWL4030 core driverDavid Brownell2008-10-191-0/+2
| | | | | | | | | | | | | | | | | | | | | | | This patch adds the core of the TWL4030 driver, which supports chips including the TPS65950. These chips are multi-function; see http://focus.ti.com/docs/prod/folders/print/tps65950.html Public specs are in the works. For now, the block diagram on the second page of the datasheet is fairly informative. There are some known issues with this core code. Most notably, the IRQ dispatching needs simplification (to use more of genirq), generalization (integrating support for secondary IRQ dispatch as well as primary, and removing the build dependency on OMAP), and then probably updating to leverage threaded IRQ support (expected to arrive in mainline "soon"). Once the core is in mainline, drivers for other parts of this chip can follow its lead and start swimming upstream too.

* mfd: Add GPIO pin configuration support for WM8350Mark Brown2008-10-131-1/+1
| | | | | | | | | | | | | | | | | | | The WM8350 provides a number of user-configurable pins providing access to various signals generated by the functions on the chip. These are referred to as GPIO pins in the device documentation but in Linux terms they are more general than that, providing configuration of alternate functions. This patch implements support for selecting the alternate functions for these pins. They can also be used as GPIOs in the normal Linux sense - a subsequent patch will add support for doing so. This code was all written by Liam Girdwood and has had minor updates and rearrangements by Mark Brown.

* mfd: Core support for the WM8350 AudioPlus PMICMark Brown2008-10-131-0/+2
| | | | | | | | | | | | | | | | The WM8350 is an integrated audio and power management subsystem intended for use as the primary PMIC in mobile multimedia applications. The WM8350 can be controlled via either I2C or SPI - the control interface is provided by a separate module in order to allow greatest flexibility in configuring the kernel. This driver was originally written by Liam Girdwood and has since been updated to current kernel APIs and split up for submission by me. All the heavy lifting here was done by Liam.

* mfd: Core support for the WM8400 AudioPlus HiFi CODEC and PMUMark Brown2008-10-131-0/+2
| | | | | | | | | | | | | | The WM8400 is a highly integrated audio CODEC and power management unit optimised for use in mobile multimedia applications. This patch adds core support for the WM8400 to the MFD subsystem. Both I2C and SPI access are supported by the hardware but currently only I2C access is implemented. The code is structured to allow SPI support to be slotted in later.
