[alsa-devel] [PATCH] ASoC: max98383: add 88200 and 96000 sampling rate support

[chunguo.feng at amlogic.com]

Hi All，

Please kindly waiver this patch, because max98383 was writed incorrectly， it should be max98373.

I have modified it, then submit new patch again.

Thanks,

BRs,
Gary.

Subject: [PATCH] ASoC: max98383: add 88200 and 96000 sampling rate support
From: fengchunguo <chunguo.feng at amlogic.com>
 
88200 and 96000 sampling rate was not enabled on driver, so can't be played.
 
The error information:
max98373 3-0031：rate 96000 not supported
max98373 3-0031：ASoC: can't set max98373-aif1 hw params: -22
