[PATCH v1 1/2] ASoC: qcom: q6dsp-lpass-ports: Add support for multiple sampling rates
Posted by Ravi.Hothi.ravi.hothi@oss.qualcomm.com 1 week, 6 days ago 
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.

This just updates the constraints, it doesn't change the actual code at
all...
