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.

The Chrome OS EC supports tunnelling through to an I2C bus on the EC. This
currently uses a copy of the I2C command code and a special 'crosec'
sub-command.
With driver model we can define an I2C bus which tunnels through to the EC,
and use the normal 'i2c' command to access it. This simplifies the code and
removes some duplication.
Add an I2C driver which tunnels through to the EC. Adjust the EC code to
support binding child devices so that it can be set up. Adjust the existing
I2C xfer function to fit driver model better.
For now the old code remains to allow things to still work. It will be

This commit adds emulation of sandbox PMIC device, which includes:
- PMIC I2C emulation driver
- PMIC I/O driver (UCLASS_PMIC)
- PMIC regulator driver (UCLASS_REGULATOR)
The sandbox PMIC has 12 significant registers and 4 as padding to 16 bytes,
which allows using 'i2c md' command with the default count (16).
The sandbox PMIC provides regulators:
- 2x BUCK
- 2x LDO
Each, with adjustable output:
- Enable state
- Voltage
- Current limit (LDO1/BUCK1 only)
- Operation mode (different for BUCK and LDO)
Each attribute has it's own register, beside the enable state, which depends
on operation mode.

This driver implements regulator operations for fixed Voltage/Current
value regulators. beside the standard regulator constraints, which are
put into the uclass platform data, a typical fixed regulator node provides
few additional properties like:
- gpio
- gpio-open-drain
- enable-active-high
- startup-delay-us
The only 'gpio' is used by this driver and is kept in structure of type
'fixed_regulator_platdata', as a device platform data (dev->platdata).
The driver implements:
- get_value
- get_current
- get_enable
- set_enable

One way to reproduce this is to bootup an Ippo-q8h board with a usb-host
cable plugged into the otg (so that it will get powered), then unplug the
usb-host cable and plug in a charger, and then do "reset" on the u-boot

board/sunxi/board.c tries to set ldo3 to 2.8v however drivers/power/axp209.c
contains an incorrect limit on ldo3 of 2.275v
The origin of the incorrect limit seems likely due to some inconsistencies
in the axp209 datasheet. ldo3 is described with different limits in
different sections. register 0x29 uses 7 bits for voltage configuration
while the 2.275v limit would apply if only 6 bits were used.
Probably this is a cut&paste error from register 0x23

And also add Kconfig option for selecting ELDO3 voltage. The reason
for having this option is that the Android kernel sets ELDO3 to
1.2V when powering up LCD in the case if 'lcd_if' configuration
variable is set to 6 (LCD_IF_EXT_DSI) in the FEX file. Most likely
to supply power for a SSD2828 chip.
However on the MSI Primo81 tablet, which is using this particular
'lcd_if = 6' setup for LCD, setting the ELDO3 voltage appears to
be unnecessary and it works regardless. Having no schematics of
this tablet, I can only guess that 1.2V is supplied to SSD2828
in some other way.

We do not use the axp209 interrupt, and at least in my mini-x (which does not
have a power button) the pwr-button pin and the irq pin are soldered together,
so if the axp209 keeps it irq asserted too long it will see a 10s pwr-button
press and hard power off the board, disabling the irqs fixes this.

The voltage setting code knows it needs to call axp221_init before calling
the various voltage setting functions.
But users of axp utility functions like axp221_get_sid() do not know this,
so the utility functions always call axp221_init() to ensure that the
p2wi / rsb setup magic has been done.
Since doing this repeatedly is quite expensive, add a check to axp221_init
so that it only does the initialization once.

Some boards use GPIO-s on the pmic, one example of this is the A13-OLinuXino
board, which uses gpio0 of the axp209 for the lcd-power signal.
This commit adds support for gpio pins on the AXP209 pmic, the sunxi_gpio.c
changes are universal, adding gpio support for the other AXP pmics (when
necessary) should be a matter of adding the necessary axp_gpio_foo functions
to their resp. drivers, and add "#define AXP_GPIO" to their header file.
Note this commit only adds support for the non device-model version of the
gpio code, patches for adding support to the device-model version are very
welcome.
The string representation for these gpio-s is AXP0-#, the 0 in the AXP0 prefix
is there in case we need to support gpio-s on more then 1 pmic in the future.
At least A80 boards have 2 pmics, and we may end up needing to support gpio-s
on both.
