2009-09-17mfd: Add support for TWL4030/5030 dynamic power switchingAmit Kucheria1-0/+13
The TWL4030/5030 family of multifunction devices allows board-specific control of the the various regulators, clock and reset lines through 'scripts' that are loaded into its memory. This allows for Dynamic Power Switching (DPS). Implement board-independent core support for DPS that is then used by board-specific code to load custom DPS scripts.

2009-09-17mfd: AB3100 OTP readoutLinus Walleij1-0/+9
This adds the ability to read out OTP (One-Time Programmable) registers in the AB3100 MFD ASIC. It's a simple sysfs file you can cat to prompt. The OTP registers of the AB3100 are used to store various device-unique information such as customer ID, product flags and the 3GPP standard IMEI (International Mobile Equipment Indentity) number.

2009-06-17mfd: add PCAP driverDaniel Ribeiro1-0/+7
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).

2009-01-04mfd: dm355evm msp430 driverDavid Brownell1-0/+8
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.

2008-10-20mfd: TWL4030 core driverDavid Brownell1-0/+14
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.

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.
