Subject: [PATCH 1/2] ASoC: fsl_micfil: Add support for i.MX8MPlus
Date:   Mon,  9 May 2022 17:14:22 +0800
Message-Id: <1652087663-1908-1-git-send-email-shengjiu.wang@nxp.com>
Precedence: bulk

On i.MX8Plus there are two updates for micfil module.

One is that the output format is S32_LE, only the 24 more
significative bits have information, the other bits are always
zero. Add 'formats' variable in soc data to distinguish the
format on different platform.
Another is that the fifo depth is 32 entries.
