[PATCH 0/4] ASoC: mediatek: mt8192-mt6359: fix I2S corrupted for RT5682
The series fixes the I2S corrupted when mt8192-mt6359 is playing and capturing via RT5682 in different formats.
The 1st and 2nd patch refactor to use asoc_substream_to_rtd(). Just realized there is such a helper for the purpose.
The 3rd patch simplies ops of Capture1 DAI link.
The 4th patch adds format constriants to the I2S to make sure the settings are symmetric.
Tzung-Bi Shih (4): ASoC: mediatek: mt8192-mt6359: use asoc_substream_to_rtd() ASoC: mediatek: mt8192: use asoc_substream_to_rtd() ASoC: mediatek: mt8192-mt6359: simply ops for Capture1 DAI link ASoC: mediatek: mt8192-mt6359: add format constraints for RT5682

Any fixes in a series should go before cleanup patches like this, it avoids any dependencies which might stop the fix being sent as a fix.

1. Uses rtd->dev to get the device. 2. Generalizes the variable name.

There is only 1 set of I2S in between MT8192 and RT5682. Adds format constraints to the corresponding DAI links to make sure the settings are symmetric.
