It looks like it was intended to allow two types of node names with the binding: - With unit address, e.g. pwm@1f000000 - With a suffix, e.g. pwm-clk However the pattern regex only correctly matches the first variant, as well as some incorrect ones. Fix the regex to match only two patterns shown above. (Either unit address starting with @ and following with one or more hexademical digit or arbitrary suffix stating with - and at least one symbol long) Fixes: 89650a1e3b6f ("dt-bindings: pwm: Convert PWM bindings to json-schema") Signed-off-by: Nikita Travkin <nikita@xxxxxxx> --- 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 3c01f85029e5..4926fe65886f 100644 --- a/Documentation/devicetree/bindings/pwm/pwm.yaml +++ b/Documentation/devicetree/bindings/pwm/pwm.yaml @@ -13,7 +13,7 @@ select: false properties: $nodename: - pattern: "^pwm(@.*|-[0-9a-f])*$" + pattern: "^pwm(@[0-9a-f]+|-.+)?$" "#pwm-cells": description: -- 2.30.2
