+title: Battery driver for CW2015 shuntless fuel gauge by CellWise.
+
+maintainers:
+ - Tobias Schramm <t.schramm@manjaro.org>
+
+description: |
+ The driver can utilize information from a simple-battery linked via a
+ phandle in monitored-battery. If specified the driver uses the
+ charge-full-design-microamp-hours property of the battery.

+properties:
+ compatible:
+ const: cellwise,cw2015
+
+ reg:
+ maxItems: 1
+
+ cellwise,battery-profile:
+ description: |
+ This property specifies characteristics of the battery used. The format
+ of this binary blob is kept secret by CellWise. The only way to obtain
+ it is to mail two batteries to a test facility of CellWise and receive
+ back a test report with the binary blob.

+ - minItems: 64
+ maxItems: 64
+
+ cellwise,monitor-interval-ms:
+ description:
+ Specifies the interval in milliseconds gauge values are polled at
+ minimum: 250
+
+ power-supplies:
+ description:
+ Specifies supplies used for charging the battery connected to this gauge
+ allOf:
+ - $ref: /schemas/types.yaml#/definitions/phandle-array
