Subject: [PATCH] ASoC: fsl_sai: Update slots number according to bclk_ratio
Date: Fri, 5 Aug 2022 14:45:26 +0800 [thread overview]
Message-ID: <1659681926-13493-1-git-send-email-shengjiu.wang@nxp.com> (raw)
The bclk_ratio is set by .set_bclk_ratio API.
bclk_ratio = slots * slot_width
So if slots is not set by .set_tdm_slot, then it can be calculated
by bclk_ratio.
