33 This driver does not auto-detect devices. You
34 devices explicitly. Please see Documentation/i
35 details.

37 The vout under- and over-voltage limits are se
38 output voltage as a positive or negative offse
39 in 50mV steps. This means that the absolute va
40 when the commanded output voltage changes. Als
41 writing to those limits since in the worst cas
42 could change at the same time as the limit is
43 unpredictable results.
