v1
Changes:
1.remove 24kHz support
2.disables micbias during suspend and remove
3.regmap resync during resume
4.make irq optional
5.cancel_delay_work during suspend and remove
Unchanged:
1.dts about reg58,59. We ask OEMs to use a specific board layout for irq
and jack detection.
a dts about it can be added, but only useful in rare situation.

* [PATCH v1 1/2] ASoC: codecs: add support for ES8326

From: Zhu Ning @ 2022-07-18 5:32 UTC (permalink / raw)
To: alsa-devel
Cc: devicetree, Zhu Ning, pierre-louis.bossart, tiwai, broonie,
Zhu Ning, David Yang
The ES8326 codec is not compatible with ES8316 and requires a dedicated driver.
Signed-off-by: David Yang <yangxiaohua@everest-semi.com>

-----
v1
Changes:
1.remove 24kHz support
2.disables micbias during suspend and remove
3.regmap resync during resume
4.make irq optional
5.cancel_delay_work during suspend and remove
Unchanged:
1.dts about reg58,59. We ask OEMs to use a specific board layout for irq
and jack detection.
a dts about it can be added, but only useful in rare situation.
