Hi Elaine, This is not the exact version I sent, and you reintroduced a "problem" that were already solved/discussed on previous versions. See below: On 24/3/21 8:16, Elaine Zhang wrote: > Convert the soc/rockchip/power_domain.txt binding document to > json-schema and move to the power bindings directory. > > Signed-off-by: Enric Balletbo i Serra <enric.balletbo@xxxxxxxxxxxxx> If you do significant is a good practice shortly describe them within [] here. > Signed-off-by: Elaine Zhang <zhangqing@xxxxxxxxxxxxxx> Note that my last version already had the Reviewed-by: Rob Herring <robh@xxxxxxxxxx> Which should be fine for merging (with probably only minor changes) and you could maintain if you don't do significant changes, but that's not the case, as I said, you are reintroducing one problem. Please review the comments already received on this patchset or similar patchsets to avoid this. > --- > .../power/rockchip,power-controller.yaml | 284 ++++++++++++++++++ > .../bindings/soc/rockchip/power_domain.txt | 136 --------- > 2 files changed, 284 insertions(+), 136 deletions(-) > create mode 100644 Documentation/devicetree/bindings/power/rockchip,power-controller.yaml > delete mode 100644 Documentation/devicetree/bindings/soc/rockchip/power_domain.txt > > diff --git a/Documentation/devicetree/bindings/power/rockchip,power-controller.yaml b/Documentation/devicetree/bindings/power/rockchip,power-controller.yaml > new file mode 100644 > index 000000000000..a220322c5139 > --- /dev/null > +++ b/Documentation/devicetree/bindings/power/rockchip,power-controller.yaml > @@ -0,0 +1,284 @@ > +# SPDX-License-Identifier: GPL-2.0-only > +%YAML 1.2 > +--- > +$id: http://devicetree.org/schemas/power/rockchip,power-controller.yaml# > +$schema: http://devicetree.org/meta-schemas/core.yaml# > + > +title: Rockchip Power Domains > + > +maintainers: > + - Elaine Zhang <zhangqing@xxxxxxxxxxxxxx> > + - Rob Herring <robh+dt@xxxxxxxxxx> Up to Rob, but I don't think Rob would like to be the maintainer.
