From: Bastien Curutchet Date: Tue, 2 Apr 2024 07:12:09 +0000 (+0200) Subject: ASoC: ti: davinci-i2s: Enable unexpected frame pulses detection X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=94d57c541dbdd350a91baeee94d3f5148e1d4dd7;p=linux.git ASoC: ti: davinci-i2s: Enable unexpected frame pulses detection McBSP can generate a SYNCERR when unexpected frame pulses are detected. The driver always disables this feature and ignore the unexpected frame pulses. Enable the generation of SYNCERR by the McBSP. Unexpected frame pulses are not ignored anymore.
