It only matches pwm-$(a-hex-number), not any string, so that shouldn't be a problem. This is needed for things like GPIO based devices (not just PWMs) which don't have any address. Pinmux nodes are going to need to adopt some sort of standard pattern we can match on. > Signed-off-by: Benjamin Gaignard <benjamin.gaignard@xxxxxx> > --- > Documentation/devicetree/bindings/pwm/pwm.yaml | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/Documentation/devicetree/bindings/pwm/pwm.yaml b/Documentation/devicetree/bindings/pwm/pwm.yaml > index fa4f9de92090..29b86886c282 100644 > --- a/Documentation/devicetree/bindings/pwm/pwm.yaml > +++ b/Documentation/devicetree/bindings/pwm/pwm.yaml > @@ -11,7 +11,7 @@ maintainers: > > properties: > $nodename: > - pattern: "^pwm(@.*|-[0-9a-f])*$" > + pattern: "^pwm(@.*[0-9a-f])*$" > > "#pwm-cells": > description: > -- > 2.15.0 >
