-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;
- }
