Schemas aren't executable. checkpatch.pl will tell you this.
okay, I will use the checkpatch.pl.

Use standard units (-ohms), not strings. For "open", just omit the property.
okay, I will.

okay, I will use standard units.

When clock detection is enabled, it will detect whether MCLKand FS are within the range. MCLK range is from 2.048MHz to 24.576MHz.FS range is from 8kHz to 96kHz. And also needs to detect the ratioMCLK_SRC/LRCK of 256, 400 or 500, and needs to detect the BCLKto make sure data is present. There needs to be at least 8 BCLKcycles per Frame Sync.- type: boolean
