Subject: [PATCH v2 1/2] ASoC: qcom: q6dsp-lpass-ports: Extend q6dsp-lpass-ports driver to support additional sampling rates
Date: Wed, 10 Dec 2025 12:21:55 +0530 [thread overview]
Message-ID: <20251210065157.2775514-2-ravi.hothi@oss.qualcomm.com> (raw)
In-Reply-To: <20251210065157.2775514-1-ravi.hothi@oss.qualcomm.com>
Expand the existing constraints in the q6dsp-lpass-ports driver
to allow a wider range of sampling rates, from 8000 Hz to 192000 Hz.
This change improves compatibility with diverse audio hardware and
provides greater flexibility for audio stream configurations.
