description:
SBS batteries by default send broadcast messages to SBS compliant chargers to
configure max. charge current/voltage. If your hardware does not have an SBS
compliant charger it should be disabled via this property to avoid blocking
the bus. Also some SBS battery fuel gauges are known to have a buggy multi-
master implementation.

SBS sbs-battery
~~~~~~~~~~
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,bq20z65
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.
- sbs,disable-charger-broadcasts: for systems without sbs compliant chargers
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>;
sbs,disable-charger-broadcasts;
