The N900 DT contains a bq27200 referencing the charger, so it should fail the DT check without the property being listed here. > .../bindings/power/supply/bq27xxx.txt | 56 ------------ > .../bindings/power/supply/bq27xxx.yaml | 86 +++++++++++++++++++ > 2 files changed, 86 insertions(+), 56 deletions(-) > delete mode 100644 Documentation/devicetree/bindings/power/supply/bq27xxx.txt > create mode 100644 Documentation/devicetree/bindings/power/supply/bq27xxx.yaml > > diff --git a/Documentation/devicetree/bindings/power/supply/bq27xxx.txt b/Documentation/devicetree/bindings/power/supply/bq27xxx.txt > deleted file mode 100644 > index 4fa8e08df2b6..000000000000 > --- a/Documentation/devicetree/bindings/power/supply/bq27xxx.txt > +++ /dev/null > @@ -1,56 +0,0 @@ > -TI BQ27XXX fuel gauge family > - > -Required properties: > -- compatible: contains one of the following: > - * "ti,bq27200" - BQ27200 > - * "ti,bq27210" - BQ27210 > - * "ti,bq27500" - deprecated, use revision specific property below > - * "ti,bq27510" - deprecated, use revision specific property below > - * "ti,bq27520" - deprecated, use revision specific property below > - * "ti,bq27500-1" - BQ27500/1 > - * "ti,bq27510g1" - BQ27510-g1 > - * "ti,bq27510g2" - BQ27510-g2 > - * "ti,bq27510g3" - BQ27510-g3 > - * "ti,bq27520g1" - BQ27520-g1 > - * "ti,bq27520g2" - BQ27520-g2 > - * "ti,bq27520g3" - BQ27520-g3 > - * "ti,bq27520g4" - BQ27520-g4 > - * "ti,bq27521" - BQ27521 > - * "ti,bq27530" - BQ27530 > - * "ti,bq27531" - BQ27531 > - * "ti,bq27541" - BQ27541 > - * "ti,bq27542" - BQ27542 > - * "ti,bq27546" - BQ27546 > - * "ti,bq27742" - BQ27742 > - * "ti,bq27545" - BQ27545 > - * "ti,bq27411" - BQ27411 > - * "ti,bq27421" - BQ27421 > - * "ti,bq27425" - BQ27425 > - * "ti,bq27426" - BQ27426 > - * "ti,bq27441" - BQ27441 > - * "ti,bq27621" - BQ27621 > -- reg: integer, I2C address of the fuel gauge. > - > -Optional properties: > -- monitored-battery: phandle of battery characteristics node > - The fuel gauge uses the following battery properties: > - + energy-full-design-microwatt-hours > - + charge-full-design-microamp-hours > - + voltage-min-design-microvolt > - Both or neither of the *-full-design-*-hours properties must be set. > - See Documentation/devicetree/bindings/power/supply/battery.txt > - > -Example: > - > - bat: battery { > - compatible = "simple-battery"; > - voltage-min-design-microvolt = <3200000>; > - energy-full-design-microwatt-hours = <5290000>; > - charge-full-design-microamp-hours = <1430000>; > - }; > - > - bq27510g3: fuel-gauge@55 { > - compatible = "ti,bq27510g3"; > - reg = <0x55>; > - monitored-battery = <&bat>; > - }; > diff --git a/Documentation/devicetree/bindings/power/supply/bq27xxx.yaml b/Documentation/devicetree/bindings/power/supply/bq27xxx.yaml > new file mode 100644 > index 000000000000..54f497c291f2 > --- /dev/null > +++ b/Documentation/devicetree/bindings/power/supply/bq27xxx.yaml > @@ -0,0 +1,86 @@ > +# SPDX-License-Identifier: GPL-2.0 > +# Copyright (C) 2020 Texas Instruments Incorporated > +%YAML 1.2 > +--- > +$id: "http://devicetree.org/schemas/power/supply/bq27xxx.yaml#" > +$schema: "http://devicetree.org/meta-schemas/core.yaml#" > + > +title: TI BQ27XXX fuel gauge family > + > +maintainers: > + - Pali Rohár > + - Andrew F.

Maybe Rob can help out here. Otherwise it's not a blocker, since the conversion is still an improvement without having explicit deprecation marks :) > + - ti,bq27500-1 - BQ27500/1 > + - ti,bq27510g1 - BQ27510-g1 > + - ti,bq27510g2 - BQ27510-g2 > + - ti,bq27510g3 - BQ27510-g3 > + - ti,bq27520g1 - BQ27520-g1 > + - ti,bq27520g2 - BQ27520-g2 > + - ti,bq27520g3 - BQ27520-g3 > + - ti,bq27520g4 - BQ27520-g4 > + - ti,bq27521 - BQ27521 > + - ti,bq27530 - BQ27530 > + - ti,bq27531 - BQ27531 > + - ti,bq27541 - BQ27541 > + - ti,bq27542 - BQ27542 > + - ti,bq27546 - BQ27546 > + - ti,bq27742 - BQ27742 > + - ti,bq27545 - BQ27545 > + - ti,bq27411 - BQ27411 > + - ti,bq27421 - BQ27421 > + - ti,bq27425 - BQ27425 > + - ti,bq27426 - BQ27426 > + - ti,bq27441 - BQ27441 > + - ti,bq27621 - BQ27621 > + > + reg: > + maxItems: 1 > + description: integer, I2C address of the fuel gauge. > + > + monitored-battery: > + description: | > + phandle of battery characteristics node. > + The fuel gauge uses the following battery properties: > + - energy-full-design-microwatt-hours > + - charge-full-design-microamp-hours > + - voltage-min-design-microvolt > + Both or neither of the *-full-design-*-hours properties must be set. > + See Documentation/devicetree/bindings/power/supply/battery.txt power-supplies: true > + > +required: > + - compatible > + - reg > +additionalProperties: false > + > +examples: > + - | > + i2c0 { > + #address-cells = <1>; > + #size-cells = <0>; > + bat: battery { > + compatible = "simple-battery"; > + voltage-min-design-microvolt = <3200000>; > + energy-full-design-microwatt-hours = <5290000>; > + charge-full-design-microamp-hours = <1430000>; > + }; > + > + bq27510g3: fuel-gauge@55 { > + compatible = "ti,bq27510g3"; > + reg = <0x55>; > + monitored-battery = <&bat>; > + }; > + }; Otherwise looks good to me. -- Sebastian
