Subject: [PATCH] ASoC: ti: davinci-i2s: Add S32_LE as support format
Git-commit: 2231b2c63f869528504195f202d9585a4f00f143
Patch-mainline: v5.4-rc1
References: jsc#SLE-16518

ASP/McBSP can support 8/16/20/24/32 bits word in theory. I have only tested
S16_LE and S32_LE, the other formats might not work so only extend the
supported formats with S32_LE for now.
