2009-01-04mfd: dm355evm msp430 driverDavid Brownell
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: Add WM8351 supportMark Brown
The WM8351 is a WM8350 variant. As well as register default changes the WM8351 has fewer voltage and current regulators than the WM8350. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@openedhand.com>

This is a fix for: twl4030-core.c:(.text+0x16a797): undefined reference to `clk_get_rate' twl4030-core.c:(.text+0x16a797): undefined reference to `clk_put' on x86 and x86_64, as the clock API is not defined on those platforms. Signed-off-by: Samuel Ortiz <sameo@openedhand.com>
2009-01-04mfd: twl4030 regulator bug fixesDavid Brownell
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 Brownell
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.

2009-01-04mfd: twl4030: cleanup symbols and OMAP dependencyDavid Brownell
Finish removing dependency of TWL driver stack on platform-specific IRQ definitions ... and remove the build dependency on OMAP. This lets the TWL4030 code be included in test builds for most platforms, and will make it easier for non-OMAP folk to update most of this code for new APIs etc. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Samuel Ortiz <sameo@openedhand.com>
2009-01-04mfd: twl4030: simplified child creation codeDavid Brownell
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.

2009-01-04mfd: Refactor WM8350 chip identificationMark Brown
Since the WM8350 driver was originally written the semantics for the identification registers of the chip have been clarified, allowing us to do an exact match on all the fields. This avoids mistakenly running on unsupported hardware. Also change to using the datasheet names more consistently for legibility and fix a printk() that should be dev_err().

2009-01-04power_supply: Add support for WM8350 PMUMark Brown
This patch adds support for the PMU provided by the WM8350 which implements battery, line and USB supplies including a battery charger. The hardware functions largely autonomously, with minimal software control required to initiate fast charging. Support for configuration of the USB supply is not yet implemented. This means that the hardware will remain in the mode configured at startup, by default limiting the current drawn from USB to 100mA. This driver was originally written by Liam Girdwood with subsequent updates for submission by Mark Brown.

2009-01-04mfd: allow reading entire register banks on twl4030David Brownell
Minor change to the TWL4030 utility interface: support reads of all 256 bytes in each register bank (vs just 255). This can help when debugging, but is otherwise a NOP. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Samuel Ortiz <sameo@openedhand.com>
2009-01-04mfd: Add AUXADC support for WM8350Mark Brown
