Hi Guenther, I'm posting v2 of my series on max31790. These are the changes from v1: 1) The driver uses regmap caching instead of local caching. 2) I got rid of the "refactor" patch and also the "pulses" patch. 3) I got rid of unnecessary whitespace changes. 4) fan*_input now returns -ENODATA when fan*_enable is 0. 5) Changed the argument of bits_for_speed_range to long. Vaclav
