[PATCH v4 0/3] Fix lpaif_type and DAI configuration for I2S interface

[PATCH v4 0/3] Fix lpaif_type and DAI configuration for I2S interface

[Mohammad Rafi Shaik]

Fix the lpaif_type configuration for the I2S interface.
The proper lpaif interface type required to allow DSP to vote
appropriate clock setting for I2S interface and also Add support
for configuring the DAI format on MI2S interfaces to allow setting
the appropriate bit clock and frame clock polarity, ensuring correct
audio data transmissionover MI2S.

changes in [v4]:
	- Updated commit message in patch v4-0003, suggested by Srinivas Kandagatla.
	- Link to V3: https://lore.kernel.org/linux-sound/20250905150445.2596140-1-mohammad.rafi.shaik@oss.qualcomm.com/

changes in [v3]:
	- Added Cc: <stable@vger.kernel.org>, suggested by Srinivas Kandagatla.
	- Added QUINARY MI2S case in patch 3, suggested by Konrad.
	- Link to V2: https://lore.kernel.org/lkml/20250905104020.2463473-1-mohammad.rafi.shaik@oss.qualcomm.com/

changes in [v2]:
	- Used snd_soc_dai_set_fmt() API to set the current clock settings,
	  instead of the default WS source setting, as suggested by Srinivas Kandagatla.
	- Link to V1: https://lore.kernel.org/lkml/20250822171440.2040324-1-mohammad.rafi.shaik@oss.qualcomm.com/

[PATCH v4 2/3] ASoC: qcom: q6apm-lpass-dais: Fix missing set_fmt DAI op for I2S

[Mohammad Rafi Shaik]

The q6i2s_set_fmt() function was defined but never linked into the
I2S DAI operations, resulting DAI format settings is being ignored
during stream setup. This change fixes the issue by properly linking
the .set_fmt handler within the DAI ops.
