-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;
