Subject: [PATCH v10 6/7] i2c: mux: ltc4306: set correct idle_state in i2c_mux_core
Date: Wed, 08 Jul 2026 14:16:18 +0200	[thread overview]
Message-ID: <20260708-i2c-mux-v10-6-09dca03c8a15@gmail.com> (raw)
In-Reply-To: <20260708-i2c-mux-v10-0-09dca03c8a15@gmail.com>

Inform the core if we intend to disconnect channels during idle.
