Subject: [PATCH] dt-bindings: mux: reg-mux: Allow zero-cell controls
Date: Mon, 21 Sep 2026 18:26:16 -0500 [thread overview]
Message-ID: <20260921232617.3130745-1-robh@kernel.org> (raw)
Some reg-mux users reference a controller without an argument cell
when there is only one mux control exposed by the provider.
Permit #mux-control-cells to be either 0 or 1 so the converted schema
matches both existing provider styles.
Assisted-by: LLM
