sunxi: power: axp818: add support for axp818 driver

2015-12-10T10:14:22+00:00

AXP818 is rsb based PMIC and used on Allwinner A83T H8 Homlet dev board.
It's registers are different and calculating reg config is different than
that of earlier axp power ICs.

DCDC1, DCDC2, DCDC3 and DCDC5 is implemented at the moment.
all other voltages can be added subsequently.
AXP datasheet is uploaded to wiki:

sunxi: power: Change axp209 LDO3 and LDO4 default to disabled

2015-10-20T16:40:27+00:00

LDO3 and LDO4 are normally either unused, or used to power csi
attached camera sensors, and as such do not need to be enabled at
boot time.

sunxi: power: Change A23/A33 aldo1 default voltage to 3.0V

2015-10-20T16:40:27+00:00

On A23 / A33 boards aldo1 is used for VCC-IO and should be 3.0V, make this
the default.

Note that this does not cause any functional changes since all sun8i
board defconfig-s already contained: CONFIG_AXP_ALDO1_VOLT=3000 .

sunxi: power: Change A23/A33 VDD-SYS default from 1.2V to 1.1V

2015-10-20T16:40:27+00:00

Change the axp223 dcdc2 / VDD-SYS default from 1.2V to 1.1V, 1.1V is the
value recommended by Allwinner and is what most fex files specify.

This has been tested on a number of A23/A33 tablets including on an
A23 Ippo-q8h-v1.2 PCB tablet which has a fex file which specifies 1.2V
(which is where our original 1.2V default comes from).

sunxi: power: Make all voltages configurable through Kconfig

2015-10-20T16:40:27+00:00

On boards with axp221/223 pmic-s we already allow configuring most
voltages. Make the Kconfig options for these also apply to boards with
axp152 / axp209 pmic-s and extend them to configure all voltages.

The Kconfig defaults are chosen so that this commit does not introduce any
functional changes.

sunxi: Kconfig-ify CONFIG_AXP152_POWER and _AXP209_POWER

2015-10-20T16:40:27+00:00

Kconfig-ify CONFIG_AXP152_POWER and _AXP209_POWER settings, removing
them from CONFIG_SYS_EXTRA_OPTIONS.

Note that sun5i boards can have either an AXP209 or an AXP152 pmic, the
Kconfig default is AXP209, boards with an AXP152 must explicitly select
this. Likewise boards without a pmic must explicitly select SUNXI_NO_PMIC
in their defconfig.

sunxi: axp221: Allow specifying dcdc2 voltage via Kconfig

2015-08-31T06:43:41+00:00

Allow specifying the axp221 dcdc2 voltage via Kconfig, this is necessary
because on some boards the 1.2V default does not work reliable.

dm: regulator: add implementation of driver model regulator uclass

2015-05-15T00:49:37+00:00

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

dm: pmic: add implementation of driver model pmic uclass

2015-05-15T00:49:37+00:00

This commit introduces the PMIC uclass implementation.
It allows providing the basic I/O interface for PMIC devices.
For the multi-function PMIC devices, this can be used as I/O
parent device, for each IC's interface. Then, each PMIC particular
function can be provided by the child device's operations, and the
child devices will use its parent for read/write by the common API.

Core files:
- 'include/power/pmic.h'
- 'drivers/power/pmic/pmic-uclass.c'

The old pmic framework is still kept and is independent.

For more detailed informations, please look into the header file.

Changes:
- new uclass-id: UCLASS_PMIC
- new config: CONFIG_DM_PMIC
