Subject: [PATCH v2 0/2] ASoC: qcom: q6dsp-lpass-ports: Expand sampling rate and PCM format constraints

This patch series expands the existing constraints in
the q6dsp-lpass-ports driver to improve compatibility
and flexibility for audio stream configurations. 

The first patch extends the supported sampling rates to cover a wider
range, from 8000 Hz to 192000 Hz, ensuring better compatibility with
diverse audio hardware and allowing more flexible audio stream setups.

The second patch adds support for the 32-bit PCM format
(SNDRV_PCM_FMTBIT_S32_LE) alongside the existing 16-bit
and 24-bit formats, enabling handling of high-resolution
audio streams and improving audio quality for supported hardware.

changes in [v2]:
	- Updated commit description as suggested by Mark Brown.
	- Link to V1 : https://lore.kernel.org/all/20251118100203.2751955-1-ravi.hothi@oss.qualcomm.com/

  ASoC: qcom: q6dsp-lpass-ports: Extend q6dsp-lpass-ports driver to
    support additional sampling rates
  ASoC: qcom: q6dsp-lpass-ports: Update constraints to support 32-bit
    PCM format
