Subject: [PATCH v1 1/2] ASoC: qcom: q6dsp-lpass-ports: Add support for multiple sampling rates
Date: Tue, 18 Nov 2025 15:32:02 +0530 [thread overview]
Message-ID: <20251118100203.2751955-2-ravi.hothi@oss.qualcomm.com> (raw)
In-Reply-To: <20251118100203.2751955-1-ravi.hothi@oss.qualcomm.com>
From: Ravi Hothi <ravi.hothi@oss.qualcomm.com>
Extend the q6dsp-lpass-ports driver to support a wider range of sampling
rates, from 8000 Hz to 192000 Hz. This improves compatibility with
diverse audio hardware and enables better flexibility for audio stream
configurations.
