- * The complex logic input threshold voltage support with a custom level

- * this setup equally well, or present it most appropriately to users.
- * So let's implement something simpler for the moment until the more
- * complex approach becomes accessible in all applications.

- * Strictly speaking the logic input threshold voltage is a property of
- * the "Logic" channel group. Again not all applications support such
- * an approach, and like to see them as global device properties.
+ * Whether the logic input threshold voltage is a config item of the
+ * "Logic" channel group or a global config item of the device. Ideally
+ * it would be the former (being strictly related to the Logic channels)
+ * but mainline applications work better with the latter, and many other
+ * device drivers implement it that way, too.
