The AXP806 has three operation modes:
- master mode: The PMIC is the first or only AXP PMIC in the system,
but is not in charge of power management, i.e. only
provides regulator functions.
- slave mode: The PMIC is the second AXP PMIC in the system, chained
to the first, or master, one.
- self-working mode: The PMIC is the only AXP PMIC in the system, and
is in charge of power sequencing.
The functional differences between these modes can be found in the
"Control and Operation" chapter of the AXP806 (in Chinese) and AXP805
(in English) datasheets. These include how the PMIC responds to external
signals, whether it takes an external voltage reference or uses its own,
and whether the EN/PWRON pin functions as an enable switch or power button.
We already support both slave and master mode. This patch adds a property
for describing the self-working mode, and reworks the description for
the mode properties.

'interrupt-parent' is often documented as part of define bindings, but
it is really outside the scope of a device binding. It's never required
in a given node as it is often inherited from a parent node. Or it can
be implicit if a parent node is an 'interrupt-controller' node. So
remove it from all the binding files.

Like axp221, axp223, axp813 the axp803 is also supporting external

The X-Powers AXP813 is a PMIC designed to be paired with Allwinner's
A83T SoC. There is also an AXP818, which is paired with the H8 SoC.
The two models seem to be identical, apart from the external markings.
This patch introduces the basic mfd and regulator bindings for the
AXP813.

The binding already lists compatibles and regulators for the AXP806,
but it is missing from the list of supported chips at the beginning.

In the binding documentation of AXP20X mfd, the compatible strings used
to be listed for three per line, which leads to some mess when trying to
add AXP803 compatible string (as we have already AXP806 and AXP809
compatibles, which is after AXP803 in ascending order).
Make the compatible strings one per line, so that inserting a new
compatible string will be directly a new line.

commit b101829a029a ("mfd: axp20x: Fix AXP806 access errors on cold boot")
was intended to fix the case where a board uses an AXP806 in slave mode,
but the boot loader leaves it in master mode for lack of AXP806 support.
But now the driver breaks on boards where the PMIC is operating in master
mode. To let the device tree describe which mode of operation is needed,
this patch introduces a new property "xpowers,master-mode".

The axp20x pmics have 2 power inputs, one called ACIN which is intended
for to be supplied via a powerbarrel on the board and one called VBUS
which is intended to be supplied via an otg connector.
In the VBUS case the pmic needs to know if the board is supplying power
to the otg connector, because then it should not take any power from
its VBUS pin. The axp209 pmic has a N_VBUSEN input pin via which the
board can signal to the pmic whether the board is supplying power to the
otg connector or not.
On the axp221/axp223 this pin can alternatively be used as an output
which controls an external regulator which (optionally) supplies
power to the otg connector from the board. When the pin is used as
output it is called DRIVEVBUS in the datasheet.
This commit adds support for the DRIVEVBUS pin as an extra pmic
controlled regulator. Since this is optional a new x-powers,drivebus dt
property is added. When this is present the misc-control register is
written to change the N_VBUSEN input pin to DRIVEVBUS output pin mode and
the extra drivebus regulator is registered with the regulator subsystem.

The DC1SW and DC5LDO regulators in the AXP221 are internally chained
to DCDC1 and DCDC5, hence the names. The original bindings used the
parent regulator names for the supply regulator property. This causes
some confusion when we actually use it in the dts:
axp221 {
/* self supplying? */
dcdc1-supply = <&dcdc1>;
dcdc5-supply = <&dcdc5>;
dcdc1: dcdc1 {
...
};
dcdc5: dcdc5 {
...
};
};
Since they are internally connected within the PMIC, their relationships
should not be visible in the device tree.
