From 0d11bab8ef3e5540dfba111947dbd8dcfb813150 Mon Sep 17 00:00:00 2001 From: Shengjiu Wang Date: Fri, 17 Jun 2022 15:44:33 +0800 Subject: [PATCH] ASoC: fsl_sai: Add support for more sample rates 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.
