What I meant to express is that I used the existing mediatek,mt7986-pinctrl.yaml file as the template to create a similar document for MT7981. I guess my English was not clear enough. Maybe better like this? "Add bindings for the MT7981 pinctrl driver. As MT7981 is simiar to MT7986, the existing mediatek,mt7986-pinctrl.yaml was used as an example to create a similar document covering MT7981." > > > Signed-off-by: Daniel Golle <daniel@makrotopia.org> > > --- > > .../pinctrl/mediatek,mt7981-pinctrl.yaml | 475 ++++++++++++++++++ > > 1 file changed, 475 insertions(+) > > create mode 100644 Documentation/devicetree/bindings/pinctrl/mediatek,mt7981-pinctrl.yaml > > > > diff --git a/Documentation/devicetree/bindings/pinctrl/mediatek,mt7981-pinctrl.yaml b/Documentation/devicetree/bindings/pinctrl/mediatek,mt7981-pinctrl.yaml > > new file mode 100644 > > index 0000000000000..e76fe0d5083a3 > > --- /dev/null > > +++ b/Documentation/devicetree/bindings/pinctrl/mediatek,mt7981-pinctrl.yaml > > @@ -0,0 +1,475 @@ > > +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) > > +%YAML 1.2 > > +--- > > +$id: http://devicetree.org/schemas/pinctrl/mediatek,mt7981-pinctrl.yaml# > > +$schema: http://devicetree.org/meta-schemas/core.yaml# > > + > > +title: Mediatek MT7981 Pin Controller > > + > > +maintainers: > > + - Daniel Golle <daniel@makrotopia.org> > > + > > +description: |+ > > Don't need '|+' unless there are line endings to preserve. > > > + The MediaTek's MT7981 Pin controller is used to control SoC pins. > > + > > +properties: > > + compatible: > > + enum: > > + - mediatek,mt7981-pinctrl > > + > > + reg: > > + minItems: 9 > > + maxItems: 9 > > + > > + reg-names: > > + items: > > + - const: gpio > > + - const: iocfg_rt > > + - const: iocfg_rm > > + - const: iocfg_rb > > + - const: iocfg_lb > > + - const: iocfg_bl > > + - const: iocfg_tm > > + - const: iocfg_tl > > + - const: eint > > + > > + gpio-controller: true > > + > > + "#gpio-cells": > > + const: 2 > > + description: | > > + Number of cells in GPIO specifier.
