From b8ae2bf5ccc66b6cc66567e4ef5b4f7220a458fe Mon Sep 17 00:00:00 2001 From: Shengjiu Wang Date: Fri, 31 Jul 2020 14:28:15 +0800 Subject: ASoC: fsl_sai: Fix value of FSL_SAI_CR1_RFW_MASK [ Upstream commit 5aef1ff2397d021f93d874b57dff032fdfac73de ] The fifo_depth is 64 on i.MX8QM/i.MX8QXP, 128 on i.MX8MQ, 16 on i.MX7ULP. Original FSL_SAI_CR1_RFW_MASK value 0x1F is not suitable for these platform, the FIFO watermark mask should be updated according to the fifo_depth.
