Re: [lm-sensors] [PATCH] hwmon: (ads7828) Make sample interval configurable

[Robert Rosengren]

Guenter and Jean, 

To sum up, my problems was related my kernel and hardware configuration, and it now works. Many thanks for your input!

However, the values retrieved from hwmon sysfs is not the same as before the regmap patch. Guenter, the byte swap for the regval retrieved by regmap_read. In what order is the bits returned from that function, because it seems as if I disabled that code I get values as I expect (i.e. before the regmap patch).

BR,
Robert
