From 3b7e11a0116c30848d44429650ad80f9cc3bd963 Mon Sep 17 00:00:00 2001 From: "Hendrik v. Raven" Date: Thu, 14 Nov 2024 12:01:26 +0100 Subject: [PATCH] ASoC: dt-bindings: simple-mux: add idle-state property simple-mux immediately activates the new output, even when it is powered down. This can be undesirable in some cases, for example when a mechanical relais is used. Adds "idle-state" property from the mux controller to select the output state to be used when the mux is powered down. Signed-off-by: Hendrik v.
