a4c8bbbc28 input: twl4030: Keypad scan and input
This allows scanning the twl4030 keypad, storing the result in a 64-byte long
matrix with the twl4030_keypad_scan function.

Detecting a key at a given column and row is made easier with the
twl4030_keypad_key function.

7d5ac91832 input: TWL4030 input support for power button, USB and charger
This adds support for detecting a few inputs exported by the TWL4030.
Currently-supported inputs are the power button, USB and charger presence.

6dc443e6d7 power: twl4030: Power off support
This adds support for powering off (the omap3 SoC) from the twl4030. This is
especially useful when the kernel does not actually power off the device using
this method but reboots and leaves it up to the bootloader to actually turn the
power off.

f3e85e4825 twl4030: device-index-specific MMC power initializations, common ramp-up delay
Not every device has multiple MMC slots available, so it makes sense to enable
only the required LDOs for the available slots. Generic code in omap_hsmmc will
enable both VMMC1 and VMMC2, in doubt.

2ed8c878eb twl4030: VMMC2 3.2V enable on MMC init
This enables the VMMC2 LDO, which powers the MMC2 device.
When the device starts from MMC2, this has already been enabled by the BootROM,
but when starting from peripheral boot (USB, UART), it is not the case.

528cdcaace omap: TWL4030 Bump VMMC1 interface voltage from 3V to 3.15V
MMC interfaces are specified to be 3.3V compatible with an operating
voltage range of 3.1V to 3.5V for SD cards. This change affects
hardware using TWL4030 (TPS6595x) PMICs and should improve the
reliability when communicating with marginally-spec'd MMC devices.
3.15V is the highest possible level for this chip.  This patch
has been tested on a Gumstix Overo board.

5a0a82f42b ARMV7: OMAP: add convenience function to set TWL4030 regulator voltages
This patch adds a function to allow one to easily set the target
voltage for the TWL4030 regulators.  It also modifies the existing
code to use this new function.  Applicable definitions are moved
out of the driver file and into the header file so that they are
generally accessible

ead39d7aa3 TWL4030: make LEDs selectable for twl4030_led_init()
Not all boards have both LEDs hooked, so enabling both on
boards with single LED will just waste power. Make it
possible to choose LEDs by adding argument to
twl4030_led_init().

Using this turn on only LEDB for pandora, leave both LEDs
on for all other boards, as it was before this patch.

fccc0fcaaa OMAP3 Move twl4030 mmc function
Because twl4030 now has its own device files, move and rename
twl4030_mmc_config.

twl4030_mmc_config initializes the twl4030 power setting to
the mmc device.  Because it is in the twl4030 power domain, move
it out of drivers/mmc/omap3_mmc.c and into drivers/power/twl4030.c.

The function was renamed to twl4030_power_mmc_init because all
the functions in this file are to have the format

twl4030_power_<device>_<action>

In this case the suffix is mmc_init so
device : mmc
action : init

2c15513010 OMAP3 Move twl4030 power and led functions
Because twl4030 now has its own device files, move exiting
omap3 power_init_r to a new location.

power_init_r is the only function in board/omap3/common.
It initializes the twl4030 power for the board and enables
the led.

The power part of the the function is moved to twl4030_power_init in
drivers/power/twl4030.c The power compilation is conditional on the
existing config variable CONFIG_TWL4030_POWER.

The led part is moved to twl4030_led_init in the new file
drivers/misc/twl4030_led.c  The led compilation is conditional on
the new config variable CONFIG_TWL4030_LED

The directory board/omap3/common was removed because power_init_r
was the only function in it.

cd7826359e TWL4030 Add power reset button
The Zoom2 power reset button is on the top right side of the
main board.  Press and hold for about to 8 seconds to completely
reset the board.

Some of the beta boards have a hardware problem that prevents
using this feature.  If is difficult to further characterize the
boards that fail.  So disable resetting for all beta boards.

The Zoom1 reset button is the red circle on the top right,
front of the board.  Press and hold the button for 8 seconds to
completely reset the board.

After analyzing beagle, it was determined that other boards
that use the twl4030 for power managment can also make use
this function.

The resetting is done by the power management part of the twl4030.
Since there is no existing drivers/power, add one.

The compilation of power/twl4030.h is controlled by the config
variable CONFIG_TWL4030_POWER
