Subject: [PATCH 01/12] soundwire: add lane field in sdw_port_runtime
Date: Mon, 4 Nov 2024 03:23:47 +0000 [thread overview]
Message-ID: <20241104032358.669705-2-yung-chuan.liao@linux.intel.com> (raw)
In-Reply-To: <20241104032358.669705-1-yung-chuan.liao@linux.intel.com>
Currently, lane_ctrl is always 0. Add a lane field in sdw_port_runtime
to indicate the data lane of the data port.
They are 0 by default.
