This commit introduces the implementation of dm regulator API. Device tree support allows for auto binding. And by the basic uclass operations, it allows to driving the devices in a common way. For detailed informations, please look into the header file. Core files: - drivers/power/regulator-uclass.c - provides regulator common functions api - include/power/regulator.h - define all structures required by the regulator Changes: - new uclass-id: UCLASS_REGULATOR - new config: CONFIG_DM_REGULATOR Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Acked-by: Simon Glass <sjg@chromium.org>

Set the voltage (mV) to program the axp221 dcdc1 at, set to 0 to
|
|
disable dcdc1. This is typically used as generic 3.3V IO voltage for
|
|
things like GPIO-s, sdcard interfaces, etc. On most boards this is

Set the voltage (mV) to program the axp221 aldo2 at, set to 0 to
|
|
disable aldo2. On sun6i (A31) boards this is typically unused and
|
|
should be disabled, if it is used for LPDDR2 it should be set to 1.8V.
|

On sun8i (A23) this is typically connected to VDD-DLL and must be set
|
|
to 2.5V.
