dd read and change voltage support for mx6.
For help, pls type "help regul"
Detail command info:
regul list - List all regulators' name
regul show all - Display all regulators' voltage
regul show core - Show core voltage in mV
regul show periph - Show peripheral voltage in mV
regul show <regulator name> - Show regulator's voltage in mV
regul set core <voltage value> - Set core voltage in mV
regul set periph <voltage value> - Set periph voltage in mV
regul set <regulator name> <voltage value> - Set regulator's voltage in
mV
Example:
MX6Q ARM2 U-Boot > regul list
Name Voltage
vddpu
vddcore
vddsoc
vdd2p5
vdd1p1
vdd3p0
MX6Q ARM2 U-Boot > regul show all
Name Voltage
vddpu 1100000
vddcore 1100000
vddsoc 1200000
vdd2p5 2400000
vdd1p1 1100000
vdd3p0 3000000
MX6Q ARM2 U-Boot > regul show periph
Name Voltage
periph: 1100000
MX6Q ARM2 U-Boot > regul show core
Name Voltage
core: 1100000
MX6Q ARM2 U-Boot > regul set core 1100000
Set voltage succeed!
Name Voltage
core: 1100000

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

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.

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
