With DT properties charge-current-limit-gpios and
charge-current-limit-mapping one can define charge current limits in uA
using up to 32 GPIOs. Add property charge-current-limit-default-microamp
which selects a default charge current limit that must be listed in
charge-current-limit-mapping.
This is helpful when the smallest possible charge current limit is 0uA. The
driver defaults to the smallest possible value at the moment, which
disables charging on probe. With the default its possible to setup a safe
charge current limit.

Add LTC4162-F/S and LTC4015 to the supported devices of LTC4162-L.
They share a common set of registers. The only differences lie in the
resolution value of the scaling factor for battery voltage and battery
current measurement, input voltage, and input current for different
battery chemistries. The differences also include the calculation of
setting and getting the actual voltage applied to the charge voltage,
as well as getting the die temperature.
This add compatible entries for ltc4162-f/s and ltc4015 and include
datasheets for new devices.

The SC27XX fuel gauge supports a low voltage alarm IRQ, which is used
for more accurate battery capacity measurements with lower voltages.
This was unfortunately never documented in bindings, do so now.
The only in-tree user (sc2731.dtsi) has had interrupts specified
since its initial fuel-gauge submission and the current kernel
driver returns an error when no interrupt is specified, so also
add it to the required list.

Just as unevaluatedProperties or additionalProperties are required at
the top level of schemas, they should (and will) also be required for
child node schemas. That ensures only documented properties are
present for any node.
Add unevaluatedProperties as needed, and then add any missing properties
flagged by the addition.

SPI and I2C bus node names are expected to be "spi" or "i2c",
respectively, with nothing else, a unit-address, or a '-N' index. A
pattern of 'spi0' or 'i2c0' or similar has crept in. Fix all these
cases. Mostly scripted with the following commands:
git grep -l '\si2c[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/i2c[0-9] {/i2c {/'
git grep -l '\sspi[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/spi[0-9] {/spi {/'
With this, a few errors in examples were exposed and fixed.
