The ES8326 audio codec has one interrupt pin for headset detection according to the datasheet. Document that in the binding. This fixes dtbs_check error: 'interrupts-extended' does not match any of the regexes: 'pinctrl-[0-9]+' Signed-off-by: Fei Shao <fshao@chromium.org> Reviewed-by: Rob Herring (Arm) <robh@kernel.org> Link: https://patch.msgid.link/20241105091910.3984381-1-fshao@chromium.org Signed-off-by: Mark Brown <broonie@kernel.org>
