My fault - there is no cr23h at all.

This part turns to be the most tricky one. For me the meaning/interpretation of
all the possible options is quite confusing. Especially when some contents
might get mirrored to different registers.
The nct6116 covers 5 fans in total, and I identified fan4 as AUXFAN1 and fan5
as AUXFAN2. So respectively, AUXFAN0 should be the same as AUXFAN and reference
to fan3.
Following, the piece of code which I hope to reflect this part of the datasheet
properly:
{ else if (data->kind == nct6116) {
int cr1a = superio_inb(sioreg, 0x1a);
int cr1b = superio_inb(sioreg, 0x1b);
int cr24 = superio_inb(sioreg, 0x24);
int cr2a = superio_inb(sioreg, 0x2a);
pwm3pin = cr24 & 0x08;
fan3pin = cr2b & 0x10;
pwm4pin = cr1a & 0x04;
if !(cr1b & 0x03) {
pwm5pin = cr2a & 0x02;
}
The registers described in the spec do not differ between pwmpin and fanpin.
Which one shall get used?
If the same content is good for in and out, is pwm4pin == fan4pin?
