WARNING: drivers/mfd/built-in.o(.text+0x1706): Section mismatch in
reference from the function sm501_register_gpio() to the function
.devinit.text:sm501_gpio_register_chip()
The function sm501_register_gpio() references
the function __devinit sm501_gpio_register_chip().
This is often because sm501_register_gpio lacks a __devinit
annotation or the annotation of sm501_gpio_register_chip is wrong.Signed-off-by: Rakib Mullick

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.This driver was originally written by Liam Girdwood, though it has been
extensively modified since then.Signed-off-by: Mark Brown

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 inputUnless 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.Signed-off-by: David 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.Signed-off-by: David 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.Signed-off-by: David Brownell

Finish removing dependency of TWL driver stack on platform-specific
