[PATCH 3/7] ASoC: fsl_sai: Add support for more sample rates

From: Shengjiu Wang
Date: Tue Jun 14 2022 - 00:26:15 EST


Add support for more sample rates, because PDM format
bitstream has higher sample rates. for example DSD512
format, the bit clock is 22.5792MHz, if the word width
is U8_LE, then the max sample rate is 2822400.
