I am not sure. Trip points are not arbitrary selectable. Hardware
have 4 predefined operating modes, if I could say.

0 = {105 C, 125 C, 145 C}
1 = {110 C, 130 C, 150 C}
2 = {115 C, 135 C, 155 C}
3 = {120 C, 140 C, 160 C}

Everything which driver could select is one of 0...3.

Rest of the comments will be fixed in next version.

Thanks,
Ivan
