Please say more about this device. Features, link to datasheet, etc.

okay. I will.

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.
