Add support for BQ20Z65 manufacturer data to the sbs-battery
driver. Implementation has been verified using the public TRM
available from [0] and tested using a GE Flex 3S2P battery.

Since normally syscon-reboot block is supposed to be a part of a system
controller, lets mark the regmap property as deprecated and recommend the
syscon-reboot node to be a sub-node of SYSCON.

Qualcomm driver updates for v5.8
This contains a large set of cleanups, bug fixes, general improvements
and documentation fixes for the RPMH driver. It adds a debugfs mechanism
for inspecting Command DB. Socinfo got the "soc_id" attribute defines
and definitions for a various variants of MSM8939.
RPMH, RPMPD and RPMHPD where made possible to build as modules, but RPMH
had to be reverted due to a compilation issue when tracing is enabled.
RPMHPD gained power-domains for the SM8250 voltage corners.
The SCM driver gained fixes for two build warnings and the SMP2P had an
unnecessary error print removed.

The power domains on the GX SoCs are very similar to G12A. The only
known differences so far are:
- The GX SoCs do not have the HHI_VPU_MEM_PD_REG2 register (for the
VPU power-domain)
- The GX SoCs have an additional reset line called "dvin"
Add a new compatible string and adjust the reset line expectations for
these SoCs.

The power domains on the 32-bit Meson8/Meson8b/Meson8m2 SoCs are very
similar to what G12A still uses. The (known) differences are:
- Meson8 doesn't use any reset lines at all
- Meson8b and Meson8m2 use the same reset lines, which are different
from what the 64-bit SoCs use
- there is no "vapb" clock on the older SoCs
- amlogic,ao-sysctrl cannot point to the whole AO sysctrl region but
only the power management related registers
Add a new compatible string and adjust clock and reset line expectations
for each SoC.

Add:
- trickle-charge-current-microamp:
Some chargers have 3 charging stages. First one when battery is almost
empty is often called as trickle-charge. Last state when battery has been
"woken up" is usually called as fast-charge. In addition to this some
chargers have a 'middle state' which ROHM BD99954 data-sheet describes as
pre-charge. Some batteries can benefit from this 3-phase charging
[citation needed].
Introduce trickle-charge-current-microamp so that batteries can give
charging current limit for all three states.
- precharge-upper-limit-microvolt:
When battery voltage has reached certain limit we change from
trickle-charge to next charging state (pre-charge for BD99954). Allow
battery to specify this limit.
- re-charge-voltage-microvolt:
Allow giving a battery specific voltage limit for chargers which can
automatically re-start charging when battery has discharghed down to
this limit.
- over-voltage-threshold-microvolt
Allow specifying voltage threshold after which the battery is assumed to
be faulty.

Modern device tree bindings are supposed to be created as YAML-files
in accordance with dt-schema. This commit replaces SYSCON reboot-mode
legacy bare text bindings with YAML file. As before the bindings file
states that the corresponding dts node is supposed to be compatible
"syscon-reboot-mode" device and necessarily have an offset property
to determine which register from the regmap is supposed to keep the
mode on reboot.

json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.
This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.
Scripted with ruamel.yaml with some manual fixups. Some minor whitespace
changes from the script.

Setting 'additionalProperties: false' is frequently omitted, but is
important in order to check that there aren't extra undocumented
properties in a binding.
Ideally, we'd just add this automatically and make this the default, but
there's some cases where it doesn't work. For example, if a common
schema is referenced, then properties in the common schema aren't part
of what's considered for 'additionalProperties'. Also, sometimes there
are bus specific properties such as 'spi-max-frequency' that go into
bus child nodes, but aren't defined in the child node's schema.
So let's stick with the json-schema defined default and add
'additionalProperties: false' where needed. This will be a continual
review comment and game of wack-a-mole.

There have been some cases of droid4 battery bulging that seem to be
related to being left connected to the charger for several weeks.
It is suspected that the 4.35V charge voltage configured for the battery
is too much in the long run, so lets limit the charge voltage to 4.2V.
It could also be that the batteries are just getting old.
We don't really want to just change the charge voltage to 4.2V as Android
may have charged the battery to 4.35V as pointed out by Pavel Machek.
To add checks for battery voltage, the driver needs to understand the
voltage it's charging at, and also needs to better understand it's
charger state. Right now it only understands connect and disconnect,
while now we need to know also a connected state but not charging.
So let's add better charger state handling with help of chrgcurr2 interrupt
for detecting charge full and retry, and add a check for battery voltage
before we start charging. And then we finally can lower the charge voltage
to 4.2V.
Note that we've been using the same register values as the Android distros
on droid4, so it is suspected that the same problem also exists in Android.
