Subject: [PATCH 2/7] soundwire: only compute BPT stream in sdw_compute_dp0_port_params
Date: Tue, 14 Oct 2025 11:14:45 +0800 [thread overview]
Message-ID: <20251014031450.3781789-3-yung-chuan.liao@linux.intel.com> (raw)
In-Reply-To: <20251014031450.3781789-1-yung-chuan.liao@linux.intel.com>
DP0 is only for BPT stream. We should not compute and update the port
params of the normal audio streams.
