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.

|
|
GPIO used for connecting the bq2425x device PG (Power Good) pin.
|
|
This pin is not available on all devices however it should be used if
|
|
possible as this is the recommended way to obtain the charger's input PG
|
|
state. If this pin is not specified a software-based approach for PG
|
|
detection is used.

|
|
description: |
|
|
The maximum current to be drawn from the charger's input (in uA).
|
|
If this property is not specified, the input limit current is set
|
|
automatically using USB D+/D- signal based charger type detection.
|
|
If the hardware does not support the D+/D- based detection, a default
|
|
of 500,000 is used (=500mA) instead.
