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.

2009-01-04mfd: dm355evm msp430 driverDavid Brownell3-0/+430
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.

2009-01-04mfd: twl4030 regulator bug fixesDavid Brownell1-10/+1
This contains two bugfixes to the initial twl4030 regulator support patch related to USB: (a) always overwrite the old list of consumers ... else the regulator handles all use the same "usb1v5" name; (b) don't set up the "usbcp" regulator, which turns out to be managed through separate controls, usually ULPI directly from the OTG controller.

2009-01-04mfd: twl4030: create some regulator devicesDavid Brownell1-10/+164
Initial code to create twl4030 voltage regulator devices, using the new regulator framework. Note that this now starts to care what name is used to declare the TWL chip: - TWL4030 is the "old" chip; newer ones have a bigger variety of VAUX2 voltages. - TWL5030 is the core "new" chip; TPS65950 is its catalog version. - The TPS65930 and TPS65920 are cost-reduced catalog versions of TWL5030 parts ... fewer regulators, no battery charger, etc. Board-specific regulator configuration should be provided, listing which regulators are used and their constraints (e.g. 1.8V only). Code that could ("should"?) leverage the regulator stuff includes TWL4030 USB transceiver support and MMC glue, LCD support for the 3430SDP and Labrador boards, and S-Video output.

Finish removing dependency of TWL driver stack on platform-specific IRQ definitions ... and remove the build dependency on OMAP.

2009-01-04mfd: twl4030: simplified child creation codeDavid Brownell1-216/+84
Minor cleanup to twl4030-core: define a helper function to populate a single child node, and use it to replace six inconsistent versions of the same logic. Both object and source code shrink. As part of this, some devices now have more IRQ resources: battery charger, keypad, ADC, and USB transceiver. That helps to remove some irq #defines that block the children's drivers code from compiling on non-OMAP platforms.

2008-11-29[ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King5-5/+5
When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.

2008-11-27[ARM] remove memzero()Russell King1-3/+3
As suggested by Andrew Morton, remove memzero() - it's not supported on other architectures so use of it is a potential build breaking bug. Since the compiler optimizes memset(x,0,n) to __memzero() perfectly well, we don't miss out on the underlying benefits of memzero(). Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-10-22mfd: twl4030 IRQ handling updateDavid Brownell3-405/+761
- 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.

2008-10-20mfd: twl4030-core irq simplificationDavid Brownell1-66/+2
Simplify twl4030 IRQ handling by removing a needless custom flow handler. The top level IRQs, from the PIH, are well suited for handle_simple_irq() ... they can't be acked or masked. Switching resolves some issues with how IRQs were dispatched. Notably, abuse of desc->status, IRQ accounting, and handling of various faults. In short, use standard genirq code. Drivers that request_irq() to the PIH will need to pay more attention to things like setting IRQF_DISABLED (since it's no longer ignored), and making I2C calls from handlers (you'll need a lockdep workaround).

2008-10-20mfd: TWL4030 core driverDavid Brownell3-0/+1273
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.
