Subject: [PATCH v1 1/2] ASoC: qcom: q6dsp-lpass-ports: Add support for multiple sampling rates
From: Ravi Hothi <ravi.hothi@....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.
