This compatible property was documented before the driver was renamed to
"SBS" (see commit e57f1b68c4 ("devicetree-bindings: Propagate
bq20z75->sbs rename to dt bindings")). The driver has continued to
support this property as an alternative to "sbs,sbs-battery", and
because we've noticed there are some lingering TI specifics (in the
manufacturer-specific portion of the SBS spec), we'd like to start using
this property again to differentiate.
In typical DT fashion, the <vendor>,<part-number> specifics should be
used ahead of the generic "sbs,sbs-battery" string, so we can handle
vendor specifics -- so document this. Language borrowed mostly from
Documentation/devicetree/bindings/power/supply/sbs_sbs-charger.txt
Also fixup the example to use this property (it's already implying that
it's "bq20z75@b"); fixup the node name to be generic ("battery", not
"<part-number>"); and fixup some whitespace.

~~~~~~~~~~
|
|
|
|
Required properties :
|
|
- compatible: "<vendor>,<part-number>", "sbs,sbs-battery" as fallback. The
|
|
part number compatible string might be used in order to take care of
|
|
vendor specific registers.
|
|
Known <vendor>,<part-number>:
|
|
ti,bq20z75
|
|
|
|
Optional properties :
|
|
- sbs,i2c-retry-count : The number of times to retry i2c transactions on i2c
|
|
IO failure.
|
|
- sbs,poll-retry-count : The number of times to try looking for new status
|
|
after an external change notification.
|
|
- sbs,battery-detect-gpios : The gpio which signals battery detection and
|
|
a flag specifying its polarity.
|
|
|
|
Example:
|
|
|
|
battery@b {
|
|
compatible = "ti,bq20z75", "sbs,sbs-battery";
|
|
reg = <0xb>;
|
|
sbs,i2c-retry-count = <2>;
|
|
sbs,poll-retry-count = <10>;
|
|
sbs,battery-detect-gpios = <&gpio-controller 122 1>;
|
|
}
